Review: Newton's Laws

Front

What unit do we measure force in?

Back

Newtons

Front

Objects with greater _____ also have more inertia.

Back

Mass

Front

What does Newton's 3rd Law state?

Back

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

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 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.

Front

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

Back

A soccer ball remains at rest until a player 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, you push the boat backward as you move forward.
