Speed & distance-time graphs

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s) or kilometers per hour (km/hr).

Front

What is the formula to calculate speed?

Back

speed = distance/time

Front

What is a distance-time graph?

Back

A distance-time graph is a visual representation that shows how the distance of an object changes over time.

Front

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

Back

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

Front

What does a straight diagonal line on a distance-time graph represent?

Back

A straight diagonal line represents constant speed, where the object is moving at a steady rate.

Front

What does a curve on a distance-time graph indicate?

Back

A curve indicates changing speed; the object is either accelerating or decelerating.

Front

What is the unit of speed?

Back

Common units of speed include meters per second (m/s) and kilometers per hour (km/hr).

Front

What does increasing speed look like on a distance-time graph?

Back

Increasing speed is represented by a curve that slopes upwards more steeply over time.

Front

What does decreasing speed look like on a distance-time graph?

Back

Decreasing speed is represented by a curve that slopes upwards less steeply over time.

Front

How do you find the distance from a speed-time graph?

Back

The distance can be found by calculating the area under the speed-time graph.
