explain work energy therom
Answers
Answer:
Work is said to be done when a force applied to an object moves that object. We can calculate work by multiplying the force by the movement of the object. In physics, we can define energy as the capacity to do work. The SI unit of energy is joules (J), which is named in honour of James Prescott Joule.

Explanation:
The principle of work and kinetic energy (also known as the work-energy theorem) states that the work done by the sum of all forces acting on a particle equals the change in the kinetic energy of the particle. … Kinetic Energy: A force does work on the block.
The work-energy theorem states that the net work done by the forces on an object equals the change in its kinetic energy.
What is the work-energy theorem equation?
The net work done on a particle equals the change in the particle's kinetic energy: W net = K B − K A .
The work energy theorem states that work done on a body is equal to the net change in its energy. (P.E or K.E) Proof: Consider a body of mass 'm' moving with an initial velocity u. Let a constant force F acting on a body changes its velocity to v.
