A change in position over time

How fast an object’s position changes over time

The measurement that combines both speed and direction

The location of an object

The product of mass multiplied by velocity

A group of objects from which you can measure a position or motion

What are the units of force

The push of the first object on the second object

The push of the second object on the fist object

Any push or pull from one object to another

When forces act on an object without changing its motion

A force that causes an object to change its motion

A force that opposes the motion of one object moving past another

An object at rest tends to stay at rest, an object in constant motion tends to stay in motion

An unbalanced force on an object is equal to the mass of the object multiplied by its acceleration

All forces occur in pairs, and these two forces are equal in strength and opposite in direction

Energy that is stored in the position, or structure of an object

The energy of a moving object

A theory that states energy can not be created or destroyed, it can only change forms
