How do you integrate with a computer? Let's start with an example. Suppose a car travels only in the x-direction. It starts at x = 0 m with a velocity of 0 m/s. If the car has a constant acceleration ...

The speed is \( \frac {20}{10} = 2~m/s\). Key fact The gradient of a distance-time graph represents speed. When displaying a journey, the vertical axis will often represent the distance from a ...

When a relationship between two variables is defined by a curve it means that the gradient, or rate of change is always varying. An average speed for a journey can be found from a distance-time graph ...
