Starting another Physics class on a Thursday morning was no different to my day until I realized that it was indeed my last TPJ day. Filled with mix emotions about whether to be happy or to be disappointed that this will be my last time writing I moved on with my day. Mr. Manning started the class off with passing back papers from previous days. He reminded the class that Hershey Park permission slips need to be handed in. This was an important reminder to me since I have not yet finished that task. After the reminder Mr. Manning left us free to work on our wave superposition example problems. The Superposition Principle is the rules that states the amplitude of the resulting pulse is the algebraic sum of the displacements of the individual pulses When two pulses are above equilibrium then the waves must be added together to create a larger pulse. When both are below the equilibrium then they must be added negatively so that they combine to make a larger pulse in the south direction. When one is above the equilibrium and one is below you subtract the below from the above to create the new pulse. These are the steps needed in superposition. After completing and checking the example problems the class was set on to work on their math calculations due Friday on their roller coaster project. The class period came to an end and Mr. Manning wished everyone a good day as they went on their way to second period.
