1. Question of the Day

3. Today’s Objectives: You will calculate how much gravitational and kinetic energy a ball has while moving in free fall. You will apply the law of energy conservation in order to check for energy lost internally.

4. Conservation of Energy A baseball is thrown up in the air and then falls back down. Place velocity vectors beside each corresponding baseball in the drawing, and draw an energy storage pie for each lettered position. A B C D E Gravitational Potential Energy Elastic Energy Kinetic Energy Internal Energy (Dissipated to Heat & Sound)

5. Without internal energy: A B C D E With internal energy: A B C D E Gravitational Potential Energy Kinetic Energy Internal Energy (Dissipated to Heat & Sound)

6. Materials: Computer w/ Logger Pro LabQuest Mini (Interface) Motion Detector Baseball Wire Basket Setup & Procedure: Conservation of Energy Lab:

7. Data Table: Conservation of Energy Lab: Mass of the Ball: (kg) Position:Time: (s) Height: (m) Velocity: (m/s) Gravitational Energy: (J) Kinetic Energy: (J) Total Energy: (J) Internal Energy: (J) After Release 0 Between Release and Top Top of Path Between Top and Catch Before Catch
