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 at a constant velocity unless acted upon by a net external 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

What is net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

As mass increases, acceleration decreases if the net force remains constant.

Front

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

Back

It continues to move at a constant velocity.

Front

Give an example of Newton's 1st Law of Motion.

Back

A soccer ball remains at rest until a player kicks it.

Front

Give an example of Newton's 2nd Law of Motion.

Back

A heavier object requires more force to accelerate than a lighter object.

Front

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

Back

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

Front

What is inertia?

Back

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