Front

What is force?

Back

A push or pull on an object that can cause it to change its velocity (speed or direction).

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. 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 mass?

Back

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

Front

What is acceleration?

Back

The rate of change of velocity of an object. It can be caused by a change in speed or direction.

Front

What is Newton's First Law of Motion?

Back

An object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity 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 friction?

Back

A force that opposes the motion of an object, caused by the contact between two surfaces.

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the more force is required to change its motion.
