Back

A reference point is a place or object used for comparison to determine if something is in motion.

Front

What does it mean if an object is in motion?

If an object is in motion, its distance from another object is changing.

Front

What is speed?

Back

Speed is the distance traveled per unit of time.

Front

What is average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

What is velocity?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity.

Front

How can motion be represented graphically?

Back

Motion can be represented on a line graph by plotting distance against time.

Front

What does a flat line on a distance-time graph indicate?

Back

A flat line indicates that the object is at rest and not moving.

Front

What does a steep slope on a distance-time graph indicate?

Back

A steep slope indicates that the object is moving quickly.
