Save guides, add subjects and pick up where you left off with your BBC account. The gradient of a velocity-time graph at a particular time gives the acceleration of the object at that time.

This is because a low Reynolds number implies a time-reversible flow: changing the sign of time is equivalent to changing the sign of the velocity, and this gives exactly the same flow in the pipe but ...

I had so much fun creating graphs for the Red Bull Stratos ... v is the magnitude of the velocity of the object The direction of this air resistance force is in the opposite direction as the ...

Figure 1: Changing temperature in California. We performed all analyses using both mean annual temperature (°C) and total annual precipitation (mm). Future temperature and precipitation ...
