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 ...

Save guides, add subjects and pick up where you left off with your BBC account. The gradient of a velocity-time graph at a particular time gives the acceleration of the object at that time.

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