Question

MOTION OF CENTRE OF MASS​

Answer 1

Answer:

The center-of-mass (COM) is the single point on a structure which characterizes the motion of the object if the object shrinks to a point mass. ... If a net force is applied to the COM the resulting motion will be translation (the object will not rotate)
