Mr. Burtness Name_____________________ Physics Conservation of Energy - Ball Bounce Lab Procedure For Data Collection 1. Weigh the ball you are using and record mass. Connect the CBR to your graphing calc. 2. Check under APPLICATIONS to see if your calc has the ranger program. If it does, skip step 3. 3. Press 2 nd Link > Enter > Receive Open the pivoting head of the CBR and press the number that corresponds to the model number of your calculator 4. Press program , choose ranger and press enter 5. From the main menu choose applications and select meters 6. From the applications menu choose ball bounce and follow calculators instruction 7. Hold the CBR at least .5 meters above the ball 8. Press enter (this triggers the ranger program). 9. Press trigger on the CBR and when the green light begins flashing release the ball. (You may move the CBR side to side to follow the ball, but be sure NOT to change the height) 10. Press enter and the graph of distance vs. time will appear on the screen. If the graph does not appear completely smooth, repeat the data collection procedure until you have accomplished your goal. When the first several consecutive bounces look good, you may use the plot-tools option to select the domain you wish to analyze. 11. ***** Use only the data for the initial fall, plus exactly 2 more complete bounces .***** 12.Exit the program to perform the following calculations. (Once you exit, do not run ranger) Procedure for Creating Graphs 1. When you exit the program time, distance and velocity are automatically plug into lists L 1 , L 2 and L 3 respectively. 2. Plug potential energy into L 4 , do this using the following equation mg L 2 L 4 (L 2 is the data for height and the reason this works is because potential energy is equal to mgh ) 3. Plug kinetic energy into L 5 , do this using the following equation 1/2m L 3 2 L 5 (L 3 is the data for velocity and the reason this works is because kinetic energy is equal to 1/2mv 2 ) 4. Plug total energy into L 6 , do this using the following equation L 4 + L 5 L 6 (L 4 and L 5 are the data for P.E. and K.E. respectively and total energy is equal to kinetic energy plus potential energy.) In the space below, accurately draw the height vs. time (L 1 , L 2 ) and velocity vs. time (L 1 , L 3 ) graphs; pay attention to their shapes and ESPECIALLY the slopes of each curve.
