Newton's Laws

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 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 inertia?

Back

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

Front

What is friction?

Back

A force that opposes motion between two surfaces that are in contact.

Front

What is the Law of Force and Acceleration?

Back

Another name for Newton's 2nd Law of Motion, which states that force equals mass times acceleration.

Front

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

Back

A soccer ball will not move until someone kicks it.

Front

What is an example of Newton's 2nd Law?

Back

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

Front

What is an example of Newton's 3rd Law?

Back

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

Front

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

Back

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