WORK
is the mechanical transfer of energy to a system or from a system by an external force on it.
1 of 9
POWER
the rate of work done or energy converted with respect to time.
2 of 9
ENERGY
the measure of the ability of an object or a system to perform work
3 of 9
CONSERVATION OF ENERGY
A law stating that energy cannot be created, or destroyed. It can only be changed into another form. For Example, if all resistive forces are ignored, the KE gained by a falling object will be equal to the loss in the object's GPE
4 of 9
MOTIVE POWER
Power used to make an object move
5 of 9
EFFICIENCY
the ratio of useful work done by a device to the total work done, or the ratio of useful energy output to total energy input. Often expressed as a percentage.
6 of 9
SANKEY DIAGRAM
A type of flow diagram that shows the major energy transfers, including energy losses, through a closed system
7 of 9
KINETIC ENERGY
Energy due to its speed
8 of 9
GRAVITATIONAL POTENTIAL ENERGY
Energy due to its level in a gravitational field
