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 over time.

Front

What two measurements are needed to calculate speed?

Back

To calculate speed, you need to know the time taken and the distance traveled.

What does a graph with a straight diagonal line represent?

Back

A straight diagonal line on a graph indicates that the object is moving at a constant speed.

Front

How can you tell if two objects are moving at the same speed on a graph?

Back

If two lines on a graph have the same slope, the objects are moving at the same speed.

What is the formula for speed?

Back

Speed = Distance / Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

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

Back

A steep slope indicates that the object is moving quickly.

Front

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

Back

A flat line on a speed-time graph indicates that the object is moving at a constant speed.
