Newtons Laws

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 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).

What is Newton's 3rd Law of Motion?

Back

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

Front

What is friction?

Back

A force that opposes the motion of an object, slowing it down.

Front

What does it mean for forces to be balanced?

Back

Forces are balanced when they 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

Forces are unbalanced when they are not equal, causing a change in 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 net force?

Back

The overall force acting on an object after all the individual forces are combined.

Front

How does mass affect acceleration?

Back

The more mass an object has, the more force is required to accelerate it.
