Question

what is kinetic energy?​

Answer 1

Answer:

In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. 

Answer 2

Kinetic Energy is the mechanical energy in a body which is in motion.

The formula of kinetic energy is :

K.E. = (1/2)×m×V^2

m=mass of the body.

V=velocity of the body
