World (0 Moon, 1 Mars, 2 Earth, 3 Neptune, 4 Jupiter)

Planet mass (Earth masses)

Planet radius (Earth radii)

How this connects to AP Physics 1 (Topic 2.6, Gravitational Force): mass is the amount of matter and does not change; weight is the gravitational force, W = mg. The surface gravity of a planet is g = GM/R², so it grows with mass and shrinks with the square of the radius.
