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 close accelerationThe rate of change in speed ...

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 ...
