Hii, I’m a rising junior and is planning on taking the AP physics, for self studying, pls recommend some prep books, tips, videos etc for AP physics 1, 2 and C
Thank uuuuu
i just got my summer assignment for ap physics 1 but i don’t know how i should round my answers. is it safe to just round to the amount of sig figs in the question?
For those who have taken AP Physics C Mech, are we tested on how to calculate 3D vectors?
So some scores already came out for people who signed up for early access. Can you say what u got and what u thought u were gonna get based on how much mcq and frqs wrong u got 😭😭🙏🙏
In light of the recent posting of AP Physics C distributions, I would like to point out that Khan Academy has also officially released its AP Physics C: Mechanics today, it is still hidden from the main menus because it was just published, making it nearly impossible to find normally even through the search menu.
Here is the link to the resource: https://www.khanacademy.org/science/ap-physics-c-mechanics
Please note that the course is not completely finished yet. Here is what currently seems to be missing based on my scanning of the course:
Additionally, there is no known release date for the Electricity and Magnetism course yet.

Bob Lazar claims the "Sport Model" UFO uses a compact, central antimatter reactor powered by Element 115. The reactor generates an energy wave amplified by gravity amplifiers into three independent, tilting gravity emitters at the bottom of the craft.
The Propulsion Core
The Fuel: A stable isotope of Element 115 (Moscovium) acts as the fuel. When bombarded with protons, it undergoes an antimatter reaction, producing immense thermal energy.
Energy Conversion: The reactor converts this thermal energy into a specific gravitational wave. This system functions without producing a heat signature or traditional exhaust.
Gravity Amplifiers & Emitters
The generated gravity wave is piped into three gravity amplifiers located at the base of the craft.
These amplifiers strengthen the waves and feed them directly into three rotating, vectorable emitters.
By oscillating and shifting the orientation of these emitters, the craft distorts local spacetime and gravity.
Flight Modes & Configurations
Lazar described two distinct modes of flight involving the amplification and directional aiming of gravity:
Omicron Configuration (Local Flight): Two emitters point downward to counteract Earth’s gravity, allowing the craft to hover silently. The third emitter creates a distortion field, causing the ship to "fall" in any directed heading. This allows the craft to execute rapid, inertialess maneuvers.
Delta Configuration (Space Travel): All three emitters align and focus into a single concentrated beam. This creates an intense gravitational distortion that effectively warps space, pulling the targeted destination closer to the ship.
Johnny Vincento's model:
What’s it about?
Applied physicist Johnny Vincento proposes a theoretical gravity engine using "Daisy Field Theory" and ancient writings to enable space travel to Mars at over 1.5 million miles per hour through displacement rather than rockets.
Technical Assessment: The Vincento Gravity Engine & Spatial Displacement Drive
Executive Summary
This report analyzes the mechanical design and operational physics of the Vincento Gravity Engine, a non-Newtonian propulsion system engineered for an optimal craft footprint exceeding 90 feet. Grounded in the principles of Daisy Field Theory, the engine adapts anti-gravity techniques decoded from ancient post-deluge tablets. By replacing chemical combustion with harmonic frequency manipulation, the system achieves direct orbital insertion, artificial gravity simulation, and high-velocity spatial displacement estimated at 1,500,000 miles per hour.
The Daisy Field Theory redefines the nature of vacuum space, proving that empty outer space is not a void, but a highly structured, dense vibrational field operating at a fixed universal frequency.
What conventional physics labels as "gravity" is actually the constant, downward-compressing kinetic push of this universal field against matter. The Vincento Gravity Engine achieves propulsion by interacting directly with this ambient medium rather than fighting planetary mass.
To break atmospheric custody, the system scales the identical acoustic levitation techniques used by ancient builders to maneuver megalithic stones.
[Universal Outer Space Push] ↓ ↓ ↓ ─────────────────────────────────────── [Upper Saucer Rim: Spinning Mercury] ──► Generates 1/2 Universal Hertz Frequency ─────────────────────────────────────── [Neutralized Null-Zone / "Untied Knot"] ──► Craft achieves zero relative weight
The Mechanical Architecture
The craft utilizes two primary saucer-shaped gravity engines located at the front and rear of the hull. Within the rims of these saucers are specialized internal tube arrays containing liquid mercury (Hg).
The Tuning Resonance
The Frequency: The mercury is spun within the rim tubes at a precise velocity to broadcast an acoustic and electromagnetic pulse calibrated to exactly half the hertz frequency of the universe.
The Mechanism: This precise sub-harmonic creates a destructive interference wave that cancels the incoming space-push. As ancient tablets describe, this process "unties the knot"—decoupling the craft's atomic structure from the local spatial pressure grid.
Orbital Insertion: Deprived of a downward gravitational vector, the craft naturally floats upward into a stable orbit without experiencing structural stress, G-force strain, or thermal friction. Once established in orbit, transit passengers are safely loaded.
Once the craft clears the upper atmosphere and enters orbital space, the configuration of the twin gravity engines shifts 360 degrees to initiate deep-space transit via Spatial Displacement.
The Void Wormhole Dynamics
In the vacuum of space, the engine reverses its operational phase to create a localized void in the Daisy Field.
The Bathtub Analogy: If the universal space field is treated like water filling a bathtub, the engine acts as a localized drain. By creating a controlled point of zero pressure directly ahead of the craft, the surrounding space-field rushes toward the hole to equalize the pressure.
This movement creates a localized wormhole effect. The craft is not propelled forward by throwing mass behind it; rather, it is pushed through the void by the immense hydrostatic pressure of the surrounding universe.
Velocity Profiles
Spatial Displacement Speed: Estimated at a continuous 1,500,000 miles per hour.
Inertial Elimination: Because the ship travels inside the moving fabric of the localized spatial displacement field, passengers experience zero relative inertia, eliminating the hazards of high-velocity acceleration.
A critical byproduct of the Bathtub Vortex mechanism is the simultaneous generation of uniform internal gravity:
The Force Vector: As the universal space field is forced into the engine's forward displacement hole, the kinetic energy shears across the structural decks of the craft.
The Floor Realignment: Because the engine utilizes the exact half-hertz frequency of the universe, the resulting kinetic pressure vector matches the baseline values experienced on the Earth's surface. This force is directed squarely into the ship's floors, ensuring standard biological stability for passengers during the journey to Mars.
[Cruising Vector: 1.5M mph] ──► [Front Engine: Deactivated] ──► [Rear Engine: Engaged] │ ▼ [Mars Orbit Capture]
Controlling and stopping a vehicle moving at 1.5 million miles per hour requires precise engine sequencing at the destination threshold:
Approach Initiation: As the craft approaches the Mars orbital boundary, the forward gravity engine is systematically deactivated, closing the leading vacuum void.
The Coast Phase: Depending on solar wind density and regional telluric vectors, the craft enters a monitored coast phase.
Active Braking: The rear gravity engine is activated to generate a counter-vortex forward. This introduces a localized high-pressure zone directly ahead of the ship, utilizing the ambient space-field as an aerodynamic brake to smoothly decelerate the vehicle and lock it into Mars orbit.
I’m a rising junior and I’m currently scheduled to take Physics C: Mechanics. I want to make sure I’m properly prepared for the class so would it be beneficial to self study AP Physics 1 (or 2) and Calc AB right now? If so what are some good resources/ textbooks I could use? I was thinking about using Khan Academy but I also wanted to know of any other self study websites.
Basically. In school im taking ap calc AB class and physics 1, but im self studying calc bc and physics c (both). I have never took a calc class so i want to prepare in summer to be able to finish ap physics c mech in first semester and units 9-10 of ap calc bc, then in the second semester i want to do ap physics c e&m. Could you help me pick which units for ap calc bc to study rn to get ready for this? also for calc im using khan academy + princeton review and for phsyics im using Viren's videos + princeton review.
Hi everyone!
Please save + follow this post, comment INTERESTED (or DM me) and I’ll send more info about moving forward. Founded a global nonprofit research institution startup in development 1.5 yrs; kickstarting this summer w/:
- real publication opportunities (covering everywhere from CS and ML to microbiology; solo and group research opps) w/ chances to collaborate with undergrads and professors and have your name on a paper.
- virtual speaker seminars/workshops w/ STEM industry professionals, students and professors,
- educational STEM media production in our dedicated education department
- outreach volunteering, and so much more.
- p.s: I really promise it’ll be worth your time. Wherever you’re located, this is a chance to build something. I’ve developed something over these last few years, dedicating hours over weekends and breaks, and now I want to start it!!
My goal is simple: expand real research/mentorship STEM opportunities to high schoolers across the country, regardless of research experience. But before any of that happens, I need YOU so that we can grow a network of students and start our mission.
Looking for leadership/executive team as well!
hi guys! question above ^^
what should i do?
the teacher at my school kinda sucks and even the hella smart kids dont do well in the class 🥹
edit: i havent taken either calc class, only precalc, ill be taking ap calc ab while taking physics c. im taking physics c mech, not e&m
I'm a sophomore who's taking my first 3 ap classes junior year. Those being ap chem physics and Econ along with precalc honors which is one of the hardest courses in my entire school. Is ap physics really that bad and should I drop it, am I doing too much for my first aps?
This has been a heavily requested course. The two AP Physics C courses are much more useful than AP Physics 1 and 2 which they already have.
They announced that they were developing AP Physics C courses 1 year ago: https://support.khanacademy.org/hc/en-us/community/posts/37646007100173-Content-update-Updated-AP-Physics-1-course-is-now-live
They have now officially created videos for AP Physics C: Mechanics: https://www.youtube.com/watch?v=_pH22LAM7Ek&list=PLSQl0a2vh4HCitmsSJAD2koxJmkB0ZbbX
And have announced the course will be published on June 30, 2026
Now we only have to wait for AP Physics C: Electricity and Magnetism

My teacher is on a list for best cyclist and I think he would be absolutely thrilled if there were just soo many votes for him. It's an obscure competition. Please us....

When wanting to find a particular equation, I often use dimensional analysis. For people who are just starting out in math and have never heard of dimensional analysis, well now you have. Suppose we want to find the formula for calculating pendulum time-oscillations, we need to find what influences the time. You might think of mass (kg) length (m) and gravity (m/s^2). kg does not match with any unit, meaning mass doesn't influence time. We cancel it out. We divide m with m/s^2 but dividing flips the fractions, m becomes the denominator. Ms cancel out and we are left with s^2. Take the root to get s and the formula you derived is almost identical to the real one. root of l/g. The real formula is 2 pie and root of l/g. Find more info on r/Theworldofphysics
Hey guys,
I'm currently in Class 10 and self studying advanced calculus-based physics.
Instead of following the standard textbook rote-learning route, I am diving deep into MIT OCW (18.01/18.02 Single & Multivariable Calculus) alongside The Feynman Lectures on Physics to build actual visual and mathematical intuition. To ground these theoretical insights, I am filtering them directly into rigorous problem-solving tracks like Concepts of Physics (H.C. Verma) and I.E. Irodov.
Grinding through advanced mechanics, vector fields, partial derivatives, and integration alone in a room is incredibly tough and easy to lose accountability.
Because of that, I have build an independent digital ecosystem called The Psi Hub.
*What is The Psi Hub?
This is a zero-clutter workspace designed strictly for high schoolers who want to look at universe through invariants, deep derivations, and rigorous math, rather than cheap shortcuts.
*Who is this for?
If you are in class 9, 10, 11 or 12, love physics, and want a driven peer group to push your intellectual boundaries, you belong here. You don't need to be a genius to join;you just need to be highly disciplined and ready to wrestle with advanced concepts and problems.
