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 ...
Speed-time graphs are very useful when describing the movement of an object. This is a velocity time graph of an object moving in a straight line due North. The displacement of this object is the area ...
