Question

Time rate of change of Kinetic energy is equal to
(a) Mars
(b) Force
(c) Work
(d) Power
​

Answer 1

Answer:

The rate of change of kinetic energy is n times (n is constant and appropriate dimension) the velocity at any moment of a particle of mass m,which moves in a straight line.

Answer 2

(c) Work is the correct answer.

Explanation:

• The rate of change of kinetic energy is n times the velocity of a particle of mass m, which starts moving in a straight line.
• The wok-energy theorem states that the net work done by the forces on an object by a net forces equals the change in kinetic energy of the object.
• Essentially kinetic energy is the energy use or motion. When things move, they can do work. Work is the force on the object as it changes a distance.
