Gravity exerts a powerful force on all of us -- relentlessly pulling us toward Earth's surface. Everything we do, from standing up and running to getting dressed and eating breakfast, requires us to expend energy, and much of that energy goes toward our struggle against gravity. However, despite the powerful force that gravity exerts, we take it for granted precisely because of its constancy. This interactive resource from the Exploratorium gives you the opportunity to imagine how the differing gravities on other celestial bodies would affect your weight.
