Question

Define - 1) Displacement 2) kinetic energy​

Answer 1

The quantity 12mv2 1 2 m v 2 in the work-energy theorem is defined to be the translational kinetic energy (KE) of a mass m moving at a speed v. (Translational kinetic energy is distinct from rotational kinetic energy, which is considered later.)
