Calculating Speed & Motion 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/h).

Front

How do you calculate average speed?

Back

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

Front

What does a distance-time graph represent?

Back

A distance-time graph shows how the distance of an object changes over time, allowing us to visualize its speed and motion.

Front

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

Back

A flat line indicates that the object is at rest, meaning it is not moving and the distance remains constant over time.

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

Back

A gentle slope indicates a low speed, meaning the object is covering a small distance over a longer period of time.

Front

What is the unit of speed in the metric system?

Back

The unit of speed in the metric system is meters per second (m/s).

Front

What is the significance of the y-axis on a distance-time graph?

Back

The y-axis represents the distance traveled by the object, measured in units such as meters or kilometers.

Front

What is the significance of the x-axis on a distance-time graph?

Back

The x-axis represents time, measured in units such as seconds or minutes.

Front

How can you determine the speed of an object from a distance-time graph?

Back

To determine the speed, calculate the slope of the line on the graph. The steeper the slope, the faster the speed.
