Newton's Laws

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 in everyday life.

Back

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

Give an example of Newton's 2nd Law in everyday life.

Back

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

Give an example of Newton's 3rd Law in everyday life.

Back

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

Front

What does inertia mean in relation to 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

Greater mass results in less acceleration for the same amount of force applied.

Front

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

Back

Force is directly proportional to acceleration and mass (F = ma).

Front

What is an unbalanced force?

Back

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