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.

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 ...

There are four key variables of motion. Acceleration (a)- the rate of change of an object’s velocity over time. Displacement ... derived using a velocity-time graph for a moving object with ...

For motion with uniform acceleration, x-t graph is a parabola while the ... the five quantities, displacement x, time taken t, initial velocity v 0 , final velocity v and acceleration a are ...
