A negative gradient shows the rate of “slowing down” or deceleration. Velocity-time graphs show velocity on the vertical axis. Acceleration is still represented by the gradient. Key fact The gradient ...

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 ...

We stop by a food truck to investigate three different ways to graph motion. Unit 2 Segment D: Graphing Motion We stop by a food truck to investigate three different ways to graph motion: position ...

Light has fascinated scientists for centuries. Galileo Galilei was the first to consider measuring its speed. In 1676, astronomer Ole Roemer made observations of the eclipses of Jupiter's moons to ...
