The state in which one object's distance from another is changing.
A place or object used for comparison to describe the position or motion of a person or object.
The length of a path between two points.
The length and direction of a straight line between starting and ending points.
A measurable quantity that has both magnitude and direction.
The distance an object travels in a certain period of time without regard to direction.
The speed of an object at any given instant.
Speed in a given direction.
The steepness of a line on a graph equal to its vertical change divided by its horizontal change.
The rate at which velocity changes with time.
A word that describes what is done on an object when a force is exerted on an object that causes it to move.
The ability to do work or cause change.
The energy that an object has due to its motion.
Stored energy that results from the position or shape of an object.
gravitational potential energy
The potential energy related to an object's height.
elastic potential energy
The energy of stretched or compressed objects.
An object's combined kinetic energy an potential energy.
law of conservation of energy
The rule that energy cannot be created nor destroyed.
The overall rate of speed at which an object moves; calculated by dividing the total distance an object travels by the total time.
Final velocity - Initial velocity/Time
Kinetic Energy =
Gravitational potential energy =
Weight X Height
Mechanical energy =
Potential energy + Kinetic energy
