Draw a velocity time graph for the following motion. A car brakes at traffic lights, its velocity changes from 9 m/s to rest in 6s. It remains at rest for 14s. It then accelerates to 12 m/s in 8s. Draw a set of axes for a velocity-time graph in your jotter.
If the acceleration is zero, then the second equation becomes s = v x t (since u = v) (never use s = v x t if a ≠ 0) The fourth Equation is simply derived from: Displacement = average velocity x time taken. or: Distance = average speed x time taken. The 4 equations consist of 5 physical quantities: distance/displacement, time, initial &

You will understand the principles of the physics of motion and explain it using words, diagrams, graphs and equations. Exploring the physics of motion, the terms acceleration, velocity and displacement have been used. What do these terms mean? Is displacement distance? Is velocity the same as speed? Quantities can be defined as vectors or scalars.
