Unit V: Virtual Simulation Assignment Pedulum Lab This assignment will allow you to demonstrate the following objectives: 4. Apply the concept of momentum conservations to daily life. 4.1 Investigate the momentum conservation in simple pendulum motion.    5.Identify the total mechanical energy conservation. 5.1 Explain the total energy conservation in simple harmonic motion. 5.2 Relate the mass and speed of the pendulum to kinetic energy and potential energy.   We are going to explore simple harmonic motion through the Pendulum Lab Interactive Simulation provided by PhET to find the relationship between the mass of the bob, the length of the string, the period of the pendulum, and the total energy of the system with respect to the released angles. You will record the period T and the vertical distance difference H in this Excel worksheet (highlighted area) for the eight cases. Use the “Pendulum Lab” Interactive Simulation located in the syllabus.   Please read the instructions for this activity in the course syllabus.  Then, complete the table below and answer the questions.  

2. Which factor between the mass M and the length L is more influencial on the period T of the pendulum based on your experiment? (10 points)   3.Which factors among the mass M, the length L, the period T, and the vertical distance difference H are related to the total energy?(10 points)     4. List the total mechanical energy E from greatest to least when the angle is 50 degrees for Cases A through D. (10 points) 5. List the total mechanical energy E from greatest to least when the angle is 10 degrees for Cases a through d. (10 points) 6. Which case has the greatest total mechanical energy E? Which case has the smallest total mechanical energy E? (10 points)     7. What is the momentum of the pendulum at the highest position? What is the momentum of the pendulum at the lowest position? Determine if the momentum is conserved or not. If not, explain why it is not conserved. (15 points)
