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.

Key fact The gradient of speed-time and velocity-time graphs represent acceleration. The area under a speed-time graph represents the distance travelled. The object is accelerating at \(\frac{8}{ ...

Since the average acceleration is defined as: The slope of the velocity-time graph is the average acceleration. You can see the fitting equation gives an average acceleration of 6 x 10 4 m/s 2.

The red bars show deceleration levels (braking) and the green, acceleration (speeding up). Mouse over any car to see its velocity and acceleration at ... The slower your reaction time, the more you ...
