Forces

Use our simulator to investigate the effect of gravity on other worlds. Then use your measurements and a bit of maths to calculate the strength of gravity in each location across the Solar System!

Many years ago, a mathematician named Johannes Kepler created a set of rules explaining planets' movement in our Solar System.

Did you know that what you weigh depends on the strength of gravity? And did you know that the strength on gravity on other planets is not the same as on Earth?
