Create meaningful variable names

Create constants for the gravitation on Earth and on the Moon. The gravitational pull on Earth is $32\mathrm{.}17$ feet$/$second$/$second$.$ On the Moon it is $5\mathrm{.}3$ feet$/$sec$/$sec$.$ If you want to use the metric system, be sure to change the plan. Note: This is just an excersise, so please don't overcomplicate it$.$
