Question

In Column I, information about the force(s) acting on a body is mentioned, while in Column II information about the motion of a body is given. Match the entries in Column II with the entries in Column I

Answer 1

$\ast$ A single force through centre of mass (COM) always perform translational motion. It cant perform rotational motion because in these case force will be '0'.

$\ast$ Equal and opposite force separated by non zero distances perform rotational motion as in case of circular motion of stone tied to thread

$\ast$ Equal and opposite forces acting at the same point cancels out and no net force and force no motion is carried.

$\ast$ A single force not through Center of mass can perform Rotation Motion because forces in this pass is non zero and its obvious it perform traslational motion as in case of block lying on floor pushed by rope not passing through center of mass.

$\ast$ We can take the case of projectile motion where center of mass perform Curvilinear motion.
