Hold one of the balls about the floor so that the bottom of the ball is at your initial height above the floor. Drop the ball. Have your partner observe the height to which the bottom of the ball bounces on the first bounce. This is called the balls rebound height. Repeat a three times and calculate the average rebound height.Record this measurement in your table on the back of the page. Repeat steps 1-3 for at least four types of ball. Recording each ofthe average heights. Calculate the initial and final potential energy for each ball. Show your calculations for one of the balls Calculate the initial and final potential energy for each ball. Show your calculations for one of the balls. Select ONE ball and allow it to bounce three times. Record the height of each bounce an dcalculate the efficiency of each bounce. Show your calculations TASK BELOW Answer the following questions which ball was the most efficient? Least efficient? Explain what it means for a ball to be efficient in this lab? Where did the \"lost\" energy go (what types of waste energy are there)? Redraw the diagram below and at each location state what type (5) of energy the ball has and/or is losing. Explain the conversions in energy that occurred as the ball is dropped AND as it bounces back up? Rate the balls from least to most efficient. Explain the relationship between the efficiency of the ball and its intended use? 5. Explain the second law of thermodynamics and explain how it applies to this lab? 6. Did each of the bounces in step 7 have the same efficiency? Explain. (Calculate the calculations for step 7 then answer the following question.)
