Background:Newton's law of Universal Gravitation tells us that the acceleration due to gravity g on the surface of a spherical object of mass M, radius R is:
In that gravity field, small jumps near the surface with launch speed v will send you up to a height
and your "hang time" off the ground will be
Exercise:This applet allows you to simulate jumping on a number of solar system objects, from the Sun (not recommended!) to Ceres, the largest asteroid. First, to find out how high you can jump on Earth:
Input the value of your vertical jump (in meter) on Earth, then select the solar system object of your choice to learn how high you would be able to jump there.
