1Work
Work done by a constant force is the product of the magnitude of the force, the magnitude of the displacement and the angle between the force and the displacement
2Positive work
The kinetic energy of the object increases
3Negative Work
The kinetic energy of the object decreases
4Work energy Theorem
The net/total work done on an object is equal to the change in the objects kinetic energy OR the work done on an object by a resultant/net force is equal to the change in the objects kinetic energy
5Principle of conservation of mechanical energy
The total mechanical energy in an isolated system remains constant
6Conservation force
A force for which the work done in moving an object between two points is independent of the path taken.
7Non conversative force
A force for which the work done in moving an objects between two points depends on the path taken
8Power
The rate at which work is done or energy is expanded
