Speed, Distance - time graph

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/h).

Front

What is a distance-time graph?

Back

A distance-time graph is a visual representation that shows how distance changes over time, allowing us to analyze the speed and motion of an object.

Front

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

Back

A horizontal line indicates that the object is stationary 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

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken: Average Speed = Total Distance / Total Time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, indicating how quickly it is speeding up or slowing down.

Front

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

Back

A curve indicates that the speed of the object is changing; it could be accelerating or decelerating.

Front

If a car travels 100 meters in 5 seconds, what is its speed?

Back

Speed = Distance / Time = 100 m / 5 s = 20 m/s.

Front

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

Back

A steep slope indicates a high speed, meaning the object is covering a large distance in a short amount of time.

Front

What is the formula to find time if speed and distance are known?

Back

Time = Distance / Speed.
