The gradient of a velocity-time graph at a particular time gives the acceleration of the object at that time. \(\text{Gradient} = \frac{{change\,in\,velocity ...

The motion of objects can be analysed using equations and graphs. These tools allow other aspects of motion such as acceleration and displacement to be determined or modelled. Forces, energy and ...

No matter how hard we try, we can't remember tomorrow. And physicists have no idea why. In hope of discovering the source of time's river, University of Surrey physicists Thomas Guff, Chintalpati ...
