Everything CCEA students need to know about speed-time graphs for GCSE Physics. BBC Homepage. Skip to content; ... The average velocity of the car over the whole journey = \(\frac{\text{total ...

A distance-time graph shows how the distance travelled by an object changes over time and can be used to calculate the speed of the object. A sloping line on a distance-time graph shows that the ...

The cart then detects motion over these lines to give position-time data. Again using the quadratic fit I can find the acceleration. In this case it gives a value of 0.1092 m/s 2 .
