Question

what do you understand by the term kinetic energy of an object? write an expression for the kinetic energy of an object.​

Answer 1

Answer:

Kinetic energy of an object is the energy possessed due to the motion of that object. it is equal to mv²/2

Answer 2

Answer:

This work done to put the body in motion is stored in the body as its kinetic energy. Hence, the kinetic energy of the body is K = 1/2 mv^2. Thus, the kinetic energy of a body is directly proportional to its mass and square of its velocity. Its SI unit is joule.
