Velocity-time graphs show how the velocity (or speed ... that the vehicle is accelerating at an increasing rate – non-uniform acceleration. A line upwards curving to become flat means that ...

2}\). A negative gradient shows the rate of 'slowing down' or deceleration. Velocity-time graphs show velocity on the vertical axis. Acceleration is still represented by the gradient.

They are afraid to embrace the power of the graph ... to find the acceleration from this distance-time data. Let's go back to our kinematic equation (assuming we start with zero velocity).

The first equation can be derived using a velocity-time graph for ... velocity of v and acceleration of a. The velocity of the body changes from A to B in the time t at a uniform rate.
