For the constant negative acceleration graphs the initial displacement is negative and the initial velocity is positive. The velocity time graphs give all three variables for motion–velocity ...

and acceleration = velocity change ÷ time. To find the distance travelled, look at the area under the graph. In the first 10 seconds this is the area of the triangle, ½ × 10 s × 40 m/s = 200 m.

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 ...
