Newton's 3 Laws of Motion

Front

What is Newton's 1st 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 2nd 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 3rd Law of Motion?

Back

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

Front

What is a Balanced Force?

Back

The net force is equal to 0 N, meaning all forces acting on an object cancel each other out.

Front

What is an Unbalanced Force?

Back

The net force does not equal 0 N, causing an object to accelerate in the direction of the net force.

Front

Give an example of Newton's 1st Law of Motion.

Back

A book resting on a table will remain at rest until someone pushes it.

Front

Give an example of Newton's 2nd Law of Motion.

Back

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

Front

Give an example of Newton's 3rd Law of Motion.

Back

When you jump off a small boat, the boat moves backward as you move forward.

Front

What is the formula for calculating force?

Back

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

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
