Question

Energy possessed by a body on account of motion is called

• A. mechanical energy
• B. potential energy
• C. kinetic energy
• D. magnetic energy

Answer 1

The correct option is C

kinetic energy

Explanation for the correct option

C: kinetic energy

Kinetic energy is the energy possessed by the body when it carries some velocity with it.

$\mathrm{Kinetic}\mathrm{enegy}=\frac{1}{2}\mathrm{x}\mathrm{mass}\mathrm{x}{\left(\mathrm{velocity}\right)}^2$

Explanation for the incorrect options

A: mechanical energy

1. Mechanical energy is due to the displacement of the body.

2. If this displacement is due to the motion of the body that means the body carries velocity with it then it would be kinetic energy.

3. If this displacement is due to the position of the body with respect to some reference level that means the body possesses potential energy.

B: potential energy

1. The energy possessed by the body due to its location or position with respect to the reference level.

2. Mathematically we can see that,

P.E = m x g x h

D: magnetic energy

This energy come into a role when a magnetic force acts on the charge particle in a magnetic field.

Thus, the energy possessed by a body on account of motion is called kinetic energy.
