Motion - equations and graphs
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 ...

Scientists reinvent equations governing formation of snowflakes, raindrops and Saturn's rings
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 ...

Our dynamic universe
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 ...
