TLF ID L7826
Observe the linear and non-linear distance–time graphs of a rocket travelling at both constant and changing velocities. Calculate the average and instantaneous velocities of the rocket over different time intervals. Notice what happens to the average and instantaneous velocities as the time intervals become smaller. Work out the relationship between these velocities and the gradients of secants and tangents. This learning object is a combination of two objects in the same series.
