Newton's Laws of Motion

Front

What is Newton's 1st Law of Motion?

Back

An object in motion stays in motion and an object at rest stays at rest unless acted on 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. (F=ma)

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

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

Back

It stays at rest.

Front

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

Back

It continues to move at the same speed and in the same direction.

Front

What is an unbalanced force?

Back

A force that causes an object to change its motion.

Front

What is a balanced force?

Back

Forces that are equal in size but opposite in direction, resulting in no change in motion.

Give an example of Newton's 3rd Law of Motion.

Back

A skateboarder pushes the ground backwards, causing the skateboard to move forward.

Front

What is an example of Newton's 2nd Law of Motion?

Back

A sports car accelerates faster than a tow truck when the light turns green.
