Further Travel Graphs

Straight line distance/time graphs

these tell us that the object is either at rest (the graph is horizontal) or moving at a steady speed either away from its starting point (+ or SW to NE slope) or returning to it (- or NW to SE slope)

Straight line velocity/time graphs

Remember, velocity – a VECTOR quantity since it has both size and direction – just means ‘speed in a particular direction’

these tell us that the object is either moving at a steady speed  (the graph is horizontal) or accelerating from low to higher speed (+ or SW to NE slope) or decelerating (more properly negative acceleration) from a higher to a lower speed over time (- or NW to SE slope)

What about curved graphs?

A distance/time graph curving upwards means that the object’s speed is increasing with time, and vice-versa.

For IG: recognise the shape of the graph only. For AS, you should be able to solve the problem
