|style="width: 50%;|Step 1 - 1. Notice where the pendulum is – is it higher, lower or at the same level as the central position?

2. Notice the graph – what are the two variables on the bar chart?
3. What do you think will happen to the pendulum next?
|style="width: 50%;|Step 2 - 4. Notice where the pendulum is – has it moved? What can you say about its movement?
5. Notice the graph – what are the variables on the bar chart? What are the values of PE and KE as compared to total energy?

7. Did you notice anything about the speed of the bob as it moves from one extreme position to another?
8. Notice the graph – what are the variables on the bar chart?
9. What has happened to the values of the KE and PE as compared to total energy?
10. What do you think is happening? Is this what you will think will happen when you try this experiment? Why? Why not? What is different?
|style="width: 50%;|Step 4 - 11. Notice where the pendulum is. This extreme position to the right is at a different height than. Why? What role does friction play and where does it come from
12. Look at the graph – what are the variables in the bar chart? Where has the thermal energy come from? What do you expect will happen to the simple pendulum?
