Motion - AQA Synergy Velocity-time graphs. ... If an object is slowing down, it is decelerating (and its acceleration has a negative value). Example. A car takes 8.0 s to accelerate from rest to ...

Remember, acceleration is the same as gradient, and acceleration = velocity change ÷ time. Look at the graph. The acceleration of the vehicle in the first 10 seconds is: ...

With this distance and time value, I can simply plug it into the kinematic equation and solve for the acceleration. This would give an acceleration of 0.1053 m/s 2 .
