Newton's Laws Review

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 with the same speed and in the same direction 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 a force?

Back

A push or pull on an object that can cause it to accelerate.

Front

What is inertia?

Back

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

Front

What is the normal force?

Back

A force that is perpendicular to the surface an object is resting on.

Front

What is friction?

Back

A force that opposes the motion of an object.

Front

What is mass?

Back

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

Front

What is weight?

Back

The force exerted by gravity on an object, calculated as weight = mass × gravity (W = mg).

Front

What is acceleration?

Back

The rate of change of velocity of an object, typically measured in meters per second squared (m/s²).
