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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

How many laws of motion did Newton formulate?

Back

Three.

Front

What happens to an object at rest if no outside forces are applied?

Back

It will stay at rest.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and force in Newton's 2nd Law?

Back

Force is equal to mass times acceleration (F=ma). A larger mass requires more force to achieve the same acceleration.

Front

In a collision between a heavy football player and a light one, who exerts more force?

Back

The heavy football player exerts more force.

Front

What is an example of Newton's 1st Law in everyday life?

Back

A book resting on a table will remain at rest until someone picks it up.

Front

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

Back

When you push down on the ground with your foot, the ground pushes you up with an equal and opposite force, allowing you to walk.
