Using Constants

Say you wanted to use the constant c (the speed of light, you could either click the constants button and choose physics, then c, or you could write "(Physics|c (m/s))". Remember to enclose all constants in parenthesis so the calculator knows that it is a constant and not a variable like x.

Sometimes constant names can get really long and hard to work with, such as "(Planets|Mars|Satellites|Phobos|Bulk Parameters|mass (kg))" just to get the mass of Phobos. If you are going to be using the number a lot, an easy work around is reassign it to a constant of your own, like this "pmass = (Planets|Mars|Satellites|Phobos|Bulk Parameters|mass (kg))". Then you can just use "pmass" in the rest of your equations.

All constants are measured in standard SI units unless specified.
