Speed & Distance-Time Graphs
Calculating speed, and reading a journey off a graph.
What this lesson covers
Speed & Distance-Time Graphs is a 10-part Class 8 Science lesson. Each part makes one point and then hands over to the next, so it can be read in a sitting or picked up again at the part you stopped on. It defines the idea in plain words before using it, works through an example step by step, breaks the topic into its parts and compares them, shows where it is used outside the textbook, names the mistakes that cost marks in an exam, ends with a recap of what to remember.
How it begins
Speed is how much distance is covered in a given time. speed = distance ÷ time. The usual units are metres per second (m/s) or kilometres per hour (km/h). Always check which the question wants.
