Physics can feel inscrutable to students; this lesson helps them understand a graphing problem by analyzing their own ...

Distance-time graphs show distance on the vertical axis and time on the horizontal axis. The gradient of a distance-time graph represents speed because gradient = \( \frac{\text{change in ...

Your everyday notion of forces probably includes pushing and pulling and similar actions. Technically, when something is pushed or pulled we say that "a force is applied to the object". What happens ...

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 ...
