Sample question 1 - Foundation and Higher. Question. The graph below shows the thinking, ... The graph is a velocity-time graph for the model rocket. Four stages are labelled on the graph.

A velocity-time (v-t) graph represents an object’s velocity (the rate of change in the object’s position) plotted against time. On this graph, the x-axis represents time (t), and the y-axis represents ...

Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or ...
