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.

Acceleration (a)- the rate of change of an object’s velocity over time. Displacement (s)- the total ... can be derived using a velocity-time graph for a moving object with an initial velocity ...

Such graphs are known as displacement-time graphs. Sections A and C show travelling away from home. Sections B and D are when the journey has paused for a rest or a wait. Section E shows the ...

Here is a velocity vs time graph for this same situation ... What about the case of a constant acceleration? We can still find the displacement as the area under the curve by using a similar ...

(d) An object is moving in positive direction till time t 1, and then turns back with the same negative acceleration. In a V-T graph, the area under the curve represents the displacement over a ...
