Exploring Distance-Time Graphs and Speed

The video tutorial explains how to create and analyze a distance-time graph using a jogger's movement as an example. It covers plotting points, understanding constant speed, and analyzing different sections of the graph, including stationary and backward motion. The tutorial also demonstrates how to calculate speed using the formula speed equals distance divided by time.

What is the name of the jogger introduced in the video?

• Mr. Brown

• Mr. Grey

• Mr. Grayson

• Mr. Green

On a distance-time graph, what does the y-axis represent?

• Acceleration

• Speed

• Distance

• Time

What does a straight sloping line on a distance-time graph indicate?

• Acceleration

• Changing speed

• Stationary object

• Constant speed

How do you calculate speed from a distance-time graph?

• Speed = Distance + Time

• Speed = Distance / Time

• Speed = Distance x Time

• Speed = Time / Distance

If a jogger travels 60 meters in 30 seconds, what is his speed?

• 2 m/s

• 4 m/s

• 1 m/s

• 3 m/s
