Speed and Motion Graphs

Front

What is the formula to calculate speed?

Back

S = d/t

Front

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

Back

The object is moving at a constant speed.

Front

What is the difference between speed and velocity?

Back

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

Front

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

Back

The object is moving quickly.

Front

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

Back

The object is at rest.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

What is the unit of speed in the metric system?

Back

Meters per second (m/s).

Front

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

Back

The object is moving back towards the starting point.

Front

How do you calculate distance if you know speed and time?

Back

Distance = Speed x Time (d = S x t).

Front

What is deceleration?

Back

Deceleration is a decrease in speed or negative acceleration.
