Knowing Newton's Laws

Front

What is Newton's First 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 a net external force.

Front

What is Newton's Second 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 Third Law of Motion?

Back

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

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

How does mass affect acceleration according to Newton's Second Law?

Back

As mass increases, acceleration decreases for a given force.

Front

What is the relationship between force, mass, and acceleration?

Back

Force equals mass times acceleration (F = ma).

Front

Can you give an example of Newton's First Law?

Back

A soccer ball will not move until a player kicks it.

Front

What happens to an astronaut in space according to Newton's First Law?

Back

The astronaut will continue to float in space indefinitely unless acted upon by another force.

Front

How does Newton's Second Law apply to a car accelerating?

Back

A car with a larger mass will require more force to achieve the same acceleration as a lighter car.

Front

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

Back

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