Newton's Laws

Front

What is Newton's first 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 second 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 third law of motion?

Back

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

Front

What is force?

Back

A push or pull on an object that can cause it to change its motion.

Front

What is mass?

Back

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

Front

What is acceleration?

Back

The rate at which an object's velocity changes over time.

Front

What is static friction?

Back

The force that keeps an object at rest and prevents it from moving.

Front

What is sliding friction?

Back

The force that opposes the motion of an object that is sliding over a surface.

Front

What happens when forces are balanced?

Back

The object remains at rest or continues to move at a constant velocity.

Front

What happens when forces are unbalanced?

Back

The object will accelerate in the direction of the net force.
