A body moving on a circular path undergoes uniform circular motion moving at a constant speed but not a constant velocity meaning the body is undergoing acceleration (a≠0) tangential velocity. Angular velocity is just how fast the body moved through a certain angle subtended at the centre and the angular displacement just the angle from point A to B on the trajectory. For me the concept is pretty much understood but the bulk formulas in this concept eat my head literally but I still have hopes

We all... lemme reframe that some of us know that when a metal surface is irradiated with radiation of sufficient high frequency electrons will be emitted from it. Now the frequency of the incident photons from the radiation determine the energy of the photoelectrons emitted from the metal surface and the intensity of the incident frequency only affects the number of photoelectrons that will be emitted provided f>=f⁰ \[frequency of the radiation is greater than or equal to the threshold frequency\] . All this is basic knowledge E=hf and hf=W⁰ + KE . Where is my main point my main point is thank you for reading js wanted to test if I understood the lecture lock in brothers and sister's peace
