Newton's Laws

Front

What is Newton's 1st Law of Motion?

Back

The Law of Inertia: 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 Law of Force and Acceleration: 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

The Law of Action/Reaction: For every action, there is an equal and opposite reaction.

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 does inertia mean?

Back

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

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it is harder to change its motion.

Front

What is the formula for Newton's 2nd Law?

Back

F = ma (Force equals mass times acceleration).

Front

What happens to an object in motion when no net force acts on it?

Back

It continues to move at a constant velocity.
