Ion Drives and Rockets

Most spacecrafts use chemical rocket engines to propel themselves around in space. Spacecrafts use chemical rockets because they produce a high impulse, which is the change in momentum produced in a given amount of time. Therefore, these engines don’t have to run for long, since they can generate the needed force to move quite quickly. The energy produced from the chemical combustion is great, but the time the reaction goes on is relatively short.

It’s more applicable in racquet or ball sports, but every sport can make use of this trait in some small way. While I’m only going to focus on sports for today, it’s actually applicable to nearly any kind of game.

Area Under the Curve

If you’ve ever had a calculus class, you may remember that the idea of an integral is to calculate the area under the curve of a function. The way this is done is by taking the sum of the infinitesimal “rectangles” that are under the curve. Each rectangle is effectively a line, but by adding them up you can create the area under a function.
