The speed-time graphs are commonly used while showcasing the basic difference between time and velocity in real-time. Whenever speed is constant with zero acceleration, a speed-time graph is drawn in order to outline the difference between speed and velocity there. Under different circumstances, w...
Change in speed per unit time Units: ms-2 Acceleration Change in speed per unit time Units: ms-2 a = vf – vi t Acceleration = Final speed – initial speed time taken Graphs: Speed versus time The slope of the graph tells us the acceleration of the object. The area under the graph ...
A curved slope means that the acceleration is changing – the object has non-uniform acceleration. Check carefully whether a graph is a speed-time graph or a distance-time graph. On true speed–time graphs, the speed has only positive values. On velocity–time graphs the velocity can be...
