Motion Detector Lab 8: Friction 10 C Last edit was 5 hours ago B IS A Materials: motion detector, wire basket, ball Procedure: Set the wire basket on top of the motion detector as shown below. Set the motion detector to ball/walk mode. 1) Measure and record the mass of the ball you plan to use in this experiment 111= 2) Hold the ball 1 meter above the surface of the table, right above the motion detector. Use a meter stick to verify the height. Hit collect to begin recording data, then drop the ball. Lab 9: Energy 1 Г 3) Take a look at your graphs, and identify a time just after the ball was droppod. From the graphs, determine the speed of the ball and the height above the detector at this time. 0.015 m/s 0.985 m h- Using these values, calculate the total energy of the ball. Remember, E-PE +KE.

From the graphs, determine the speed of the ball and the height above the detector at this time. 4.27 m/s 0.025 m Lab 8: Friction C h- Using these values, calculate the total energy of the ball. Remember, E - PE +KE. Show your calculation below. 5) Take a look at your graphs again, and identify a time about halfway between when the ball was dropped and the ball landed on the basket. From the graphs, determine the speed of the ball and the height above the detector at this time. 2.49 m/s 0.653 m F h- Using these values, calculate the total energy of the ball. Remember, E-PE +KE. Show your calculation below. 6) You should have obtained roughly the same value of the total energy in steps 3-5. How close were your measured total energies? What effects might cause the total energy to change as the ball falls towards the ground? Lab 9: Energy 1 Lab 10: Energy 2 - O H +Phys 6 Group 4- Google Sheets X + 1883 - ET PGO Y - Σ.
