Pre-Lecture Lesson 1.2: Life and Energy

After throwing the ball in the air, it eventually converted the gained gravitational potential energy back into kinetic energy as it fell back down. What happened to that kinetic energy when the ball comes to a halt when it hits the table?

— The energy was converted into thermal kinetic energy (it heated up the ball and table surface during the impact slightly)
— The energy was converted into sound (kinetic energy associated with vibrations of air molecules)
