This gives a much longer time to record the motion so that it can easily be accomplished with a stop watch. Here you can see I have a low-friction cart on a slightly inclined track.
A journey describes the motion of an object over time. A journey can be represented using a distance-time graph. The graph will show when an object is moving and when it is stationary. The graph ...
Example This distance-time graph shows the first ten seconds of motion for a car. The average speed over the 10 seconds = gradient of the line from (0, 0) to (10, 200) = 200 10 = 20 m / s.
