Question

The energy possessed by a body by the virtue of its motion is called ______

(a) Kinetic energy

(b) Potential energy

(c) Total energy

(d) Motion energy

I got this question in semester exam.

I'm obligated to ask this question of Introduction to Work, Energy and Power topic in portion Work, Energy and Power of Physics – Class 11

Answer 1

Right choice is (a) Kinetic energy

To explain: The kinetic energy of a body emerges due to its motion. More specifically, the velocity of a body decides the amount of kinetic energy it has. Usually, the kinetic energy of a body with mass m is given as K.E. = \(\Big(\frac{1}{2}\Big)\)mv^2, where v is the velocity of the body.
