Front

What is force?

Back

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

Front

What is motion?

Back

The change in position of an object over time.

Front

What is inertia?

Back

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

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 an unbalanced 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

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is the unit of force?

Back

Newton (N).

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

What is mass?

Back

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