Performance Assessment #3 Elena was experimenting with the kinetic energy of two balls of roughly the same volume (size), a basketball and a bowling ball. She noticed that as he rolled each ball across the floor, it was much easier to roll the basketball than the bowling ball. She also noticed that when he rolled each ball into an empty cardboard box, the box moved farther when the bowling ball hit it than it did when the basketball hit it. She decided to collect some data which you will find in the data table. Use this information to answer the questions. Data Table Trial 1. 2 3 Distance Basketball Moved the Cardboard Box (m) 1.5 1.7 1.6 Distance Bowling Ball Moved the Cardboard Box (m) 3.2 3 3.1 1. Describe how Elena's data supports the concept that kinetic energy increases as the mass of an object increases. 2. Predict what would happen to the box if you performed the same experiment but used a Styrofoam ball roughly the same size as the other two. Explain.
