Force-any push or pull on an object

Unbalanced force-forces that cause a change in an object’s motion

Balanced force-forces that result in a net force of zero on an object

Friction-a force between two objects in contact that opposes an object’s motion

Coefficient of friction-a ratio of the force of friction between two objects to the normal force on an object

Centripetal force-a force that makes a body follow a circular path

Circular motion-a circular path or circular orbit

Torque – the product of the force applied to an object times the perpendicular distance from the applied force to the center of the axis of rotation.
