Force & Motion and Newton's Laws

Front

What is Force?

Back

A push or pull on an object.

Front

What is Motion?

Back

The change in position of an object over time.

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 Net Force?

Back

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

Front

How do you calculate Net Force?

Back

Net Force = Total Forces acting in one direction - Total Forces acting in the opposite direction.

Front

What is the unit of Force?

Back

Newton (N).

Front

What is Mass?

Back

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

Front

What is Acceleration?

Back

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