# Force

Force A push or pull
Net force The total amount of force on an object from two sources. Includes direction.
Friction The force opposing motion. It slows an object down.
Balanced force Wen net force = 0 N. No motion occurs.
Unbalanced Force Net force is greater than 0 N; motion occurs.
Gravity The force that pulls objects to the center of Earth. 9.86 m/s/s
Newtons Unit of measure describing force
Weight Mass x Acceleration of Gravity. Measured using a spring scale
Inertia The tendency for an object to resist a change in motion.
Newton's First Law of Motion Also known as the Law of Inertia. An object at rest stays at rest unless acted upon by an outside force. An object in motion stays in motion until acted upon by an outside force.
Newton's Second Law of Motion An object's acceleration/motion depends on the mass of the object and the force between them.
Newton's Third Law of Motion Each action has an equal but opposite reaction.
