• Lab Report Energy Transfer: Gravitational Potential Energy to Kinetic Energy Faatimah Ally SPH3U-TK June 08, 2022 Purpose When a basketball bounces its bounce loses momentum by transferring energy elsewhere. 2 This study source was downloaded by 100000861003072 from CourseHero.com on 04-05-2023 11:13:49 GMT -05:00 https://www.coursehero.com/file/186818054/SPH3U-Unit2Assignment-AllyFaatimahdocx/ This means when you dribble the basketball, you must continually replace the transferred energy by pushing down on the ball. But what happens to the said "lost" energy? As we know from physics, energy is not really lost, it just changes form. Procedure Basketball Hard floor or pavement to bounce ball on Observations When a basketball bounces, it has two different types of energy: kinetic energy and potential energy. Kinetic energy is the energy an object has when in motion. Any object that is moving has kinetic energy. A fast-moving basketball has more kinetic energy than a slowmoving basketball. But a basketball that is not moving at all has no kinetic energy. Potential energy is the energy stored in an object due to its height above the ground. When you hold a basketball at waist level, it has some potential energy. If you hold it higher, such as up over your head, it has even more potential energy. Likewise, a basketball resting on the floor has no potential energy. If you drop the basketball, the force of gravity pulls it down, and as the ball falls, its potential energy is converted to kinetic energy. As the ball gets closer to the ground, its potential energy decreases. But, the ball also speeds up, so its kinetic energy increases. As stated earlier, when a basketball hits the ground, it "loses" some energy. Based on the law of conservation of energy, energy cannot be lost, but it changes form. When a basketball hits the floor, a portion of the kinetic energy that the ball has is transferred into another form of energy
