Front

Which law explains why the driver "keeps moving forwards, even though the car has stopped"?

Back

Newton's First Law of Motion (Law of Inertia) states that an object in motion will stay in motion unless acted upon by an external force.

Which one of Newton’s Laws of Motion best explains why the dishes do not move when the table cloth is removed?

Back

Newton's Law of Inertia explains that objects at rest stay at rest unless acted upon by an external force.

Front

What is Newton's First Law known as?

Back

The Law of Inertia.

Front

What is Newton's Third Law?

Back

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

Front

Forces always act in equal and opposite pairs. Which law does this statement refer to?

Back

Newton's Third Law of Motion.

Front

What does Newton's Second Law state?

Back

Force equals mass times acceleration (F=ma).

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

Back

A passenger lurches forward in a car when it suddenly stops.

Front

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

Back
