Therefore, to avoid the use of decimals, in such cases it is more suitable using the inverse of period, known as Frequency, f, to represent the time-related phenomena. When an object rotates very fast around a fixed point, period results in a very small number. The time neccessary to make one complete revolution around a fixed point is called Period, T. Therefore, a rotational motion implies moving around a circle whose centre and radius are fixed. Kinematics of Rotational Motion Revision NotesĪ circular (rotational) motion involves the rotation of a particle about a fixed point in space by always keeping the same distance from this fixed point. Equations of all abovementioned quantities (there are more than one equation for each quantity).The meaning and formula of centripetal acceleration.The relationship between linear and rotational quantities.
In these revision notes for Kinematics of Rotational Motion, we cover the following key points:
