Understanding Motion and Force

Front

Newton's First Law

Back

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

Front

Newton's Second Law

Back

F = ma (Force equals mass times acceleration)

Front

Newton's Third Law

Back

For every action, there is an equal and opposite reaction.

Front

Force

Back

A push or pull on an object.

Front

Friction

Back

A force that opposes motion between two surfaces in contact.

Front

Gravity

Back

A force that attracts two bodies toward each other.

Front

Inertia

Back

The tendency of an object to resist changes in its state of motion.

Front

Mass

Back

The amount of matter in an object.

Front

Weight

Back

The force of gravity acting on an object's mass.

Front

Acceleration

Back

The rate of change of velocity of an object.
