But we can ask a simpler question: Does the new Einstein theory give equations of motion which are consistent with experience ? That is, do we obtain, in the first approximation, the Lorentz ...

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 ...

with Navier-Stokes equations. These are two fundamental descriptions of fluid motion dating back to the middle of the 18th and the middle of the 19th centuries, respectively. The resulting ...
