This Grade 5 gravity worksheet uses word problems to compare Earth gravity to Moon gravity at one-sixth and Mars gravity at about 0.4 of Earth. Four multiple-choice items and five fill-in-the-blank questions ask students to calculate weights for astronauts, rovers, and dogs. Each problem reinforces NGSS 5-PS2-1 thinking and builds Grade 5 fluency with simple gravity math today. Grade 5 students master gravity reasoning.
