1

Work-energy theorem

The work done on an object by a net force is equal to the change in the objects kinetic energy

2

Conservative force

Work done in moving an object between two points is independent of the path taken

3

Non-conservative force

Work done in moving an object between two points is dependent of the path taken

4

Principle of conservation of mechanical energy

Total mechanical energy in an isolated system remains constant.

5

Power

rate at which work is done or energy is expended
