Force and Motion

Front

Equal forces acting in opposite directions

Back

balanced force

Front

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Back

Newton's First Law

Front

Force opposing motion through air

Back

air resistance

Front

Forces causing a nonzero net force that alters motion

Back

unbalanced forces

Front

Amount of matter in an object

Back

mass

Front

Motion of a falling object under gravity

Back

Free fall

Front

Force = mass x acceleration

Back

Newton's Second Law

Front

A push or pull on an object

Back

force

Front

Object's resistance to motion change

Back

inertia

Front

Force/speed of movement

Back

momentum
