Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is speed?

Back

Speed is the distance traveled by an object in a given amount of time.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What is a distance-time graph?

Back

A distance-time graph shows how the distance of an object changes over time.

Front

What does it mean when an object is at rest?

Back

An object is at rest when it is not moving and its position does not change.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its speed or 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 a smooth surface?

Back

A smooth surface has less friction, allowing objects to move more easily.

Front

What happens to an object's motion when it experiences a net force?

Back

When an object experiences a net force, it will accelerate in the direction of the net force.
