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 unless acted upon by an outside force.

Front

What is Newton's 2nd Law of Motion?

Back

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

When you push down on the ground while standing up, which law explains your upward movement?

Back

Newton's 3rd Law.

Front

What happens to an object at rest when no external force acts on it?

Back

It stays at rest.

Front

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

Back

It continues to move at a constant velocity.

Front

In bowling, why do the pins stay at rest until the ball hits them?

Back

According to Newton's 1st Law, they will stay at rest until acted upon by a force.

Front

If a car accelerates, what does Newton's 2nd Law tell us about the relationship between force, mass, and acceleration?

Back

The acceleration of the car is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is an example of Newton's 3rd Law in everyday life?

Back

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

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.
