Unit V: Virtual Simulation Assignment
Pendulum Lab
This assignment will allow you to demonstrate the following objectives:
- 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.
| Case | L[m] | M[kg] | Angle |
| a | 0.5 | 0.5 | 10 |
| b | 0.5 | 1.5 | 10 |
| c | 1 | 0.5 | 10 |
| d | 1 | 1.5 | 10 |
We are going to explore simple harmonic motion through the Pendulum Lab provided by PheT to find out 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 the Excel spread worksheet (in the highlighted area) for eight cases. For example, Case A is when the length L is 0.5 m, the mass M is 0.5 kg, the angle is 50 degrees, and so on, as shown below:
| Case | L[m] | M[kg] | Angle |
| A | 0.5 | 0.5 | 50 |
| B | 0.5 | 1.5 | 50 |
| C | 1 | 0.5 | 50 |
| D | 1 | 1.5 | 50 |
