Energy - Caelyn Rawls Flashcards
The energy a moving object has because of its motion
Kinetic Energy
Stored energy due to its position
Potential Energy
Energy stored by something that can stretch or compress
Elastic Potential Energy
Energy stored in chemical bonds
Chemical Potential Energy
Energy stored by objects due to their position above earths surface
Gravitational Potential Energy
This states that energy cannot be created or destroyed
Law Of Conservation Of Energy
The transfer of energy that occurs when a force makes an object move
Work
The amount of work done in one second
Power
A device that makes doing work easier
Machine
The force that is applied to the machine
Input Force
The force applied by the machine
Output Force
The ratio of the output force to the input force
Mechanical Advantage
A measure of how much of the work put into a machine is changed into useful output work by the machine
Efficiency
A machine that does work with only one movement of the machine
Simple Machine
A bar that is free to pivot or turn around a fixed point.
Lever
