1. A body is said to be performing a G.P.M if its motion is a combination of linear and rotational motion.
2. In any G.P.M, for a given instant, there is a point in the plane from which the body appears to perform only rotational motion.
3. This point is called ICR (instantaneous centre of rotation).
4. Properties:
   
   • For the given instant, velocity of ICR is zero.
   • The velocity of the particle is tangential to the line joining the particle and ICR.
     ICR changes every instant.
5. Example:
