WebA rubber ball will bounce better off concrete than a glass ball, but the COR of glass-on-glass is a lot higher than rubber-on-rubber because some of the energy in rubber is lost to heat when it is compressed. When a rubber ball collides with a glass ball, the COR will depend entirely on the rubber. WebJan 14, 2024 · That leaves less kinetic energy to be converted to gravitational potential energy when the ball rebounds, so the height of the rebound is less than the initial drop height. The bounce may excite sound waves in the surface, thus giving it some energy. Agree that sound energy is another loss of macroscopic kinetic energy.
What factors affect the efficiency of the bounce of a ball?
WebMay 24, 2024 · energy transfer efficiency = (useful output ÷ total input ) × 100 The Attempt at a Solution In my case of a ball released from 1.2m then bouncing to 0.64m, COR=sqrt(2gh/2gH) = 0.73 (fairly elastic). I know that COR is a ratio of the ball velocity before/after impact, therefore also of the kinetic energy before/after. WebDec 1, 2010 · Best Answer. Copy. Well, right before you are about to push it or while it is sitting at the top of a hill, the ball has potential energy. This means the ball has to … city lights lounge in chicago
What kind of energy does a rolling bowling ball have? - Answers
WebOct 28, 2015 · These waves will bounce around the system until it reaches equilibrium, and this energy will not be converted back into the original kinetic energy, meaning that the system won't bounce back to its original height. The wave energy here in the spring system is the analog of the heat in your bouncing ball. WebIntroduction. When a ball falls, its gravitational potential energy is transformed into kinetic energy; likewise, after a bounce, the ball rises into the air and its kinetic energy is … Web“bouncing ball” lab part one: potential and kinetic energy materials: 1 tennis ball 1 meterstick student roles: dropper: drops ball to begin observation, then observes how the speed of the falling ball changes after each bounce measurer 1: measures and records the greatest height that the ball reaches after its 1st bounce and its 3rd bounce measurer … city lights judge judy
