The distance and direction of an object's change in position from the starting point.

The speed and direction of a moving object.

Property of a moving object that equals its mass times its velocity.

Rate of change of velocity that can be calculated by dividing the change in the velocity by the time it takes the change to occur.

Acceleration of an object toward the center of a curved or circular path.

A push or pull on an object

Sum of all the forces that are acting on an object.

Force that opposes the sliding motion between two touching surfaces.

Attractive force between two objects that depends on the masses of the objects and the distance between them.

A region of space in which every point has a physical quantity, such as a force.

Gravitational force exerted on an object.

States that an object moving at a constant velocity keeps moving at that velocity unless an unbalanced force acts on it.

States that the acceleration of an object is in the same direction as the net force on the object, and that the acceleration equals the net force divided by its mass.

States that when one object exerts a force on a second object, the second object exerts a force on the first object that is equal in strength and in the opposite direction.

Force that opposes the motion of objects that move through air.

The maximum speed an object will reach when falling through a substance, such as air.

Describes the fall of an object on which only the force of gravity is acting.

A force that is directed toward the center of a curved or circular path.

States that if no external forces act on a group of objects, the total momentum does not change.
