gradient = \(\frac{change~in~y}{change~in~x} = \frac{change~in~speed}{change~in~time} = \) \( \frac{change~in~metres~per~second}{change~in~seconds}\) = metres per ...

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 ...

Time is how long something takes to happen. The distance, speed and time triangle is an easy way to remember the formulae to help you work out problems. 1) A zombie walks at a pace of 2km/h. There is ...
