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

Acceleration depends on two variables: the mass of the object and the amount of force applied.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is a force?

Back

A push or a pull that can cause an object to move, stop, or change direction.

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces are not equal, causing a change in motion of the object.

Front

What is acceleration?

Back

The rate at which an object changes its velocity.

Front

What is mass?

Back

The amount of matter in an object, usually measured in kilograms.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's 2nd Law, Force = Mass x Acceleration (F = ma).

Front

What is inertia?

Back

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