Newton's Laws

Front

What happens when an unbalanced force acts on an object?

Back

The force changes the motion of the object.

Front

According to Newton’s second law of motion, what is force equal to?

Back

Force is equal to mass times acceleration.

Front

Why is it easier to push a child on a swing than an adult?

Back

Because the adult has more inertia.

Front

Which law is best described by the concept of inertia?

Back

Newton's 1st Law.

Front

What is a force?

Back

Any push or pull on an object.

Front

What does Newton's 1st Law state?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

What is the formula for Newton's second law of motion?

Back

F = m * a (Force = mass times acceleration).

Front

What is inertia?

Back

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

Front

What does Newton's 3rd Law state?

Back

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

Front

What is mass?

Back

The amount of matter in an object, which affects its inertia.
