Physicists use the displacement formula to find an object's change in position. It sounds simple, but calculating displacement can quickly get complicated. Let's break it down using some solved ...

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 ...

If an object moves along a straight line, its motion can be represented by a velocity-time graph. The gradient of the line is equal to the acceleration of the object. Describe the motion of the ...
