PHYSICS - Forces - Average Speed

The video tutorial explains how to calculate speed by dividing distance by time, using examples of a runner and Usain Bolt to illustrate speed variability. It differentiates between average and instantaneous speed, using cars and speed cameras as examples. The tutorial provides examples of calculating average speed, including a dog running and a car in traffic, and explains how to use distance-time graphs for these calculations.

What happens to a car's average speed when it encounters traffic?

How can you calculate the average speed from a distance-time graph?
