Differential calculus: linear graphs
TLF ID L7819
Observe the linear distance–time graph of a rocket travelling at a constant velocity. Calculate the average and instantaneous velocity of the rocket over different time intervals. Notice how as each time interval becomes smaller the rocket's average velocity is equivalent to its instantaneous velocity. Work out how the gradient of the distance–time graph is related to the average and instantaneous velocities. This learning object is one in a series of ten objects. Some objects in the series are also packaged as combined learning objects.
