Now I have a car that starts off with a velocity of 5 m/s but increases up to 15 m/s during a time interval of 7 seconds. For this case, it doesn't have a constant velocity—but it does have an ...

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 ...

If we have a speed-time or velocity-time graph, the distance travelled can be estimated by finding the area. Example. The velocity of a sledge as it slides down a hill is shown in the graph.
