1. Energy Calculations Graphing Potential, Kinetic & Total Energies Using Pendulum

2. Potential Energy Mass = 100g =0.1kg

3. Height The height is the height of the pendulum from its lowest point of swing at any given angle. height = l – (l)cos θ θ height L (length)

4. Total Energy TE=PE + KE Hint: The total energy is equal to the Initial Potential Energy and will remain the same if there were NO friction

5. Potential Energy PE =mgh

6. Speed (Horizontal) Speed = mg(l)cos θ θ height L (length)

7. Time (Period) Time (period) =

8. Use Center graph line for angle 0°. Graph the first half of the pendulum swing to 0°.

10. Mirror the points in reverse to complete the graph
