Compare your values to the values from someone who used a different celestial body than you. What do you notice? Did any celestial bodies create problems due to having too much or too little gravity? When we double the mass of the weight, what happens to the force of gravity on the mass? When we double the mass of the weight, what happens to the stretch of the spring? When we double the mass of the weight, what happens to the spring force of the spring? When we double the mass of the weight, what happens to the elastic potential energy of the spring
