Object Ball Clips Paper 1.96 Height (m) 1m 1m 1m GPE (J or N-m) 0.98 0.39 0.08 2. Calculate: For each object, substitute the values you know into the gravitational potential energy equation to solve for weight. Record each object's weight in the fourth column. Weight (N) 3.73 4.32 4.04 3. Predict: Suppose the clips were placed on the 5-m shelf. What would their gravitational potential energy be? (Show your work.) Ball: Use the Gizmo to check your answer. 4. Calculate: An object's weight is determined by its mass (m) and the acceleration due to gravity (g) affecting that object: w = mg. On Earth, g = 9.8 m/s. A. What are the masses (in kilograms) of the three objects on the Gizmo? (Note: 1 N = 1 kg x m/s) Clips: Paper: B. Suppose a 4,000-kg elephant is hoisted 20 m above Earth's surface. What will the elephant's gravitational potential energy be? (Show your work in the space below.)
