Question 10 what is energy it is change in velocity produces no light produces no cold no changes in velocity

Energy = Change in velocity

Explanation:

Energy is the change in velocity. The rate at which work is done is called power. Its SI unit is watts.

Work done and energy both are equivalent. Both have same SI unit i.e. joules. The mathematical expression for the work done is given by :

d is the displacement

Since, F = ma

And

It is clear from above formula that the work done or the energy is directly proportional to the change in velocity. So, the correct option is (A).
