Overview
Students should be able to: Show that speed is a scalar; quantity while velocity and acceleration are vectors. Calculate resultant using simple examples of motion of objects with one or two changes in direction Show that speed is a scalar; quantity while velocity and acceleration are vectors. Calculate resultant using simple examples of motion of objects with one or two changes in direction Show on a (v-t) graph the motion of a body with: Uniform velocity, Uniform acceleration, Variable acceleration/ instantaneous velocity Deduce the distance covered between any time intervals on the graph in (3) above.
