What happens to an object when a force is applied?

Back

The object's motion can change, which includes speeding up, slowing down, or changing direction.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is the difference between speed and velocity?

Back

Speed is how fast an object is moving, while velocity includes both speed and direction.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

How does mass affect the force needed to change an object's motion?

Back

Greater mass requires a greater force to achieve the same change in motion.

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.
