Newton's Three Laws of Motion

Front

What are Newton's Three Laws of Motion?

Back

1. First Law: An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force. 2. Second Law: Force equals mass times acceleration (F = m x a). 3. Third Law: For every action, there is an equal and opposite reaction.

What is the First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

What is the Second Law of Motion?

Back

Force equals mass times acceleration (F = m x a). This means that the acceleration of an object depends on the mass of the object and the amount of force applied.

Front

What is the Third Law of Motion?

Back

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

Front

What force pulls objects towards the Earth?

Back

Gravity.

How does the mass of an object affect its motion according to Newton's Second Law?

Back

The greater the mass of an object, the more force is required to accelerate it.

Front

What happens to a moving object if no unbalanced force acts on it?

Back

It will remain in motion.

Front

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

Back

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

Front

What is an example of Newton's Second Law in action?

Back

Pushing a shopping cart: the harder you push (more force), the faster it accelerates.

Front

What is an example of Newton's Third Law in action?

Back

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