Question

What are the factors on which $K.E.$ of a body depends? Explain.

Answer 1

1. The kinetic energy of a body of mass $\text{'}m\text{'}$ and moving with velocity $\text{'}v\text{'}$ is given by $\frac{1}{2}m{v}^2$
2. Hence the KE of a moving body depends on

1. Mass of the body

2. Velocity of the body

3.Since the kinetic energy of a body depends on its mass and velocity, therefore, heavy bodies moving with high velocities have more kinetic energy, than the slow-moving bodies of small mass.
