Understanding Newton's Laws of Motion

Front

Newton's First Law

Back

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

Front

Newton's Second Law

Back

Force equals mass times acceleration.

Front

Newton's Third Law

Back

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

Front

Inertia

Back

Resistance of an object to change its state of motion.

Front

Example of First Law

Back

A book on a table stays still until pushed.

Front

Example of Second Law

Back

Pushing a car requires more force than pushing a bike.

Front

Example of Third Law

Back

Jumping off a boat pushes the boat backward.

Front

Mass

Back

Amount of matter in an object. Unit measure = grams

Front

Acceleration

Back

Change in velocity over time. Unit measure = m/s2

Front

Force

Back

A push or pull on an object. Unit measure = Newtons
