Newton's Laws Examples

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 another name for Newton's 1st Law?

Back

The Law of Inertia.

Front

What does Newton's 2nd Law of Motion state?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied. It can be expressed as 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

When a car suddenly stops, passengers lurch forward because their bodies want to continue moving.

Front

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

Back

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

Front

How does Newton's 3rd Law apply to swimming?

Back

When a swimmer pushes the water backward, the water pushes the swimmer forward.

Front

What is inertia?

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 will be harder to change its motion.

Front

What happens to a sled when a child stops pulling it?

Back

The sled continues to move forward due to its inertia until acted upon by another force (like friction or a collision).
