Key fact The gradient of speed-time and velocity-time graphs represent acceleration. The area under a speed-time graph represents the distance travelled. The object is accelerating at \(\frac{8}{ ...

gradient = \(\frac{change~in~y}{change~in~x}\) = \( \frac{change~in~distance}{change~in~time} \) = \(\frac{change~in~metres}{change~in~seconds} \) = m/s. The gradient ...

But here is the problem ... of the graph. OK, let's do a simple experiment and use a graph to find a mathematical model. Constant Acceleration We are going to measure distance and time for ...
