1.3 plot and explain distance - time graphs A distance time graph has distance on the y axis (usually in metres ) and time on the x axis (usually in seconds). The gradient of the line (change in y/ change in x) is the speed. If the line is flat then the object is stationary. 1.04 know and use the relationship between average speed, distance and time speed (m/s) = distance travelled (m)/ time taken (s) 1.05 practical: investigate the motion of everyday objects such as toy cars and tennis balls Apparatus: stopwatch and meter rule 1.mark the start and end positions for the know distance 2.use a meter rule to measure the distance 3.line up front of car with start point, release and start timer 4.move eyes to end point 5.stop timer when front of car passes end point 6.improve by repeating and averaging 7.make sure car starts from stationary 8.calculate average speed using: average speed = distance travelled/ time taken 1.06 know and use the relationship between acceleration, velocity and time 1.07 plot and explain velocity - time graphs on a velocity time graph the velocity - time graph the velocity is on the y axis (usually in m/s) and time is on the x axis (usually in s).
