9. a) average speed is the speed over the entire period of the journey, and is calculated as: total distance/total time taken Instantaneous speed is the speed at a particular moment in time. On a Speed-Time graph, the instantaneous speed can be taken from any point which lies on the line (e.g in the graph above, at time = 4 seconds, instantaneous speed = 32m/s) b) speed is a scalar quantity, i.e. it has magnitude (size) but no particular direction. Velocity is a vector quantity, i.e. it has magnitude and direction. 10. a = Δv/Δt = 24m/s / 6s = 4m/s2
