Question

what do you mean by kinetic energy derive an expression for kinetic energy of an object of mass m moving with velocity v ​

Answer 1

Explanation:

Kinetic energy is the energy of mass in motion. The kinetic energy of an object is the energy it has because of its motion. ... Note that energy is a scalar quantity, i.e., it does not depend on direction, and it is always positive.

K = 1/2 mv^2
