Reference Point | place or object used for comparison to determine if something is in motion |
Distance | length of a path between two points |
Displacement | length and direction that an object has moved from its starting point |
Vector | a quantity that consists of both a magnitude and a direction |
Speed | the rate at which an object moves |
Velocity | speed in a given direction |
Acceleration | rate at which velocity changes |
Scalar | an object that only has magnitude not direction |
Energy | the ability to do work or cause change |
Kinetic Energy | energy that an object has due to motion |
Potential Energy | stored energy that results from the position or shape of an object |
Gravitational Energy | Potential energy that depends on the height of an object |
Elastic Energy | the energy of stretched or compressed objects |
Mechanical Energy | kinetic or potential energy associated with the motion or position of an object |
Conservation of Energy | a principle stating that energy cannot be created or destroyed, but can be altered from one form to another. |
Work | force exerted on an object that causes it to move |
