Work
The product of force and the distance moved in the direction of the force (in J).
1 of 8
Principle of conservation of energy
The total energy of a closed system remains constant - energy cannot be created or destroyed.
2 of 8
Energy
The capacity for doing work (in J).
3 of 8
Kinetic Energy
The energy associated with an object as a result of its motion.
4 of 8
Gravitational potential energy
The capacity for doing work as a result of an object's psoition in a gravitational field.
5 of 8
Uniform gravitational field
A gravitational field in which the field lines are parallel and the value for g remains constant.
6 of 8
Power
The rate of work done (in W).
7 of 8
Efficiency
The ratio of useful output to total input of energy.
