Acceleration = change of velocity ÷ time ... direction, of a body before it accelerates (before it changes speed or direction)., \(\text{u}\) = 0 m/s (because it was at rest – not moving ...

Here, the rate of change of its velocity changes at different points in time. (a) An object is moving in a positive direction with ... In a V-T graph, the area under the curve represents the ...

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 ...
