Review Newton's Laws

Front

What is Newton's First Law of Motion?

Back

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

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is force?

Back

A push or pull on an object that can cause it to accelerate.

Front

What is inertia?

Back

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

Front

What is an example of Newton's First Law?

Back

A passenger lurches forward in their seat when a car suddenly stops.

Front

What does 'equal and opposite' mean in Newton's Third Law?

Back

It means that forces always occur in pairs; if one object exerts a force on another, the second object exerts a force of equal strength in the opposite direction.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

What is an example of Newton's Second Law?

Back

If you push a shopping cart, it accelerates more if it is empty than if it is full.
