Speed and Motion Graphs

Front

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

Back

Constant speed.

Front

What does a horizontal line on a distance-time graph represent?

Back

Not moving.

Front

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

Back

Moving at a fast speed.

Front

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

Back

Moving at a slow speed.

Front

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

Back

Moving back towards the starting point.

Front

What is acceleration?

Back

The rate of change of velocity over time.

Front

What is deceleration?

Back

A decrease in speed or negative acceleration.

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What does the area under a speed-time graph represent?

Back

The distance traveled.

Front

What is the difference between speed and velocity?

Back

Speed is scalar (magnitude only), while velocity is vector (magnitude and direction).
