Answer»

work done =change in kinetic energy This is the work energy theorm.

The relationship between Final KE abetween work done on a body and its kinetic energy is very nicely captured byWork-Kinetic Energy Theorem.

This theorem essentially says that if a force is exerted on a body, the force does work on the body (often described as a dot product of Force and displacement). Then this work done is equal to the difference and initial KE. Or Work Done by a Force, W = KE (final) - KE (initial).
