#Notice where the pendulum is – is it higher, lower or at the same level as the central position?
#Notice the graph – what are the two variables on the bar chart?
#What do you think will happen to the pendulum next?
#Notice where the pendulum is – has it moved? What can you say about its movement?
#Notice the graph – what are the variables on the bar chart?
#What are the values of PE and KE as compared to total energy?
#Notice where the pendulum is – has it moved? Is it higher or lower than the central position?
#Did you notice anything about the speed of the bob as it moves from one extreme position to another?
#Notice the graph – what are the variables on the bar chart?
#What has happened to the values of the KE and PE as compared to total energy?
#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?
#Notice where the pendulum is. This extreme position to the right is at a different height than before. Why? What role does friction play and where does it come from
#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?
