How do you calculate distance and revolutions?
You must buy a bicycle computer and attach it to your bike. They can calculate various things- speed, distance, RPM, time, tempertature, altitude, speed increase or decrease
How are acceleration and speed alike?
They are not alike but they are related. A positive acceleration means an increase in velocity (speed). A negative acceleration means a decrease in velocity. Velocity (speed) has the dimensions of distance / time. Acceleration has the dimensions of distance/time2 or velocity/time.
What is the difference between direct proportion and indirect proportion?
Two variables are said to be in direct proportion if, when you increase one by some multiple, the other also increases by that same multiple. Alternatively, both decrease by the same proportion. Two variables are in indirect (or inverse) proportion if an increase in one of them is associated with a decrease in the other, and conversely. The proportional change in both is the same. For example, if I change the speed at which I am driving, then the distance that I can cover in a fixed amount of time will change in the same proportion. Double my speed then double the distance, quadruple speed and quadruple distance, halve the speed and halve the distance. So speed and distance are directly proportional. Now think of speed and the time taken to do a fixed distance. Double my speed and halve the time. Halve the speed then double the time. So time taken is inversely proportional to speed.
How would decreasing the time it takes you to run a certain distance of your speed?
Decreasing the time, for the same distance, means you increase your speed. Remember that speed is distance / time.
If your speed triples you need times the distance to stop?
If your speed triples, the distance required to stop increases by a factor of nine. This is because stopping distance is proportional to the square of the speed. Therefore, if you increase your speed by three times, the stopping distance becomes three squared, which equals nine times the original distance.
