Velocity vs time graph
Doodle Science teaches you physics in a less boring way in almost no time! This one starts with speed, the gradient of a distance vs time graphs, then moves on to acceleration, the gradient of a velocity vs time graph and the area under this graph (distance travelled). (1.56)
