1.A law is an observation; a theory is the explanation of that observation.
2.A theory requires experimentation under various conditions. A law has no such requirements.
3.A theory may become obsolete with time. This is not the case with a law.
4.A theory can be replaced by another better theory; however, this never happens with a law.
5.A theory may be strong or weak according to the amount of evidence available. A law is a universally observable fact.

Kinetic energy is produced when the amount of work done on an object relative to its change in energy.
Explanation:
A strong connection is present between within work as well as energy. When work is performed on an object energy is added along with it . Energy can be defined as ability to do certain amount of work on the other hand work means to change in energy . Kinetic energy is produced when the object is in moving position and potential energy is produced when the object is at resting position.
