Newton's 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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied. It can be expressed with the formula F = ma (Force = mass x acceleration).

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

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

Back

A soccer ball will not move until a player kicks 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 in the context of Newton's 1st Law?

Back

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

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

As mass increases, acceleration decreases if the same amount of force is applied.

Front

What is the relationship between force, mass, and acceleration?

Back

Force is directly proportional to the product of mass and acceleration.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion.
