An interaction between objects that are usually expressed as a push or pull

What does the word Net Force mean?

The sum of all forces or the left over force

What does the word Balanced Forces mean?

All the forces on an object cancel each other out.

What does the word Unbalanced Forces mean?

The forces on an object do not cancel each other out.

What does the word Friction mean?

The resistance force resulting from two objects moving past each other.

What does the word Mass mean?

The amount of matter in an object

What does the word Weight mean?

A measurement of the force exerted by Earth’s gravity

What does the word Gravity mean

The force of attraction between all objects with mass

What does the word Inertia mean?

The tendency of objects to resist changes in motion

What does the word Newton (N) mean?

A made up unit of force in the metric system

What does the word Momentum mean?

A measurement of motion that equals the product of mass and velocity

What is Newton’s first law of motion?

that an object at rest will stay at rest or an object in motion will stay in motion unless acted upon by an outside force.

What is Newton’s 2nd Law of Motion?

the mathematical relationship which says acceleration is directly proportional to net force and inversly proportional to mass.

What is Newton’s 3rd law of motion?

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