Study Guide

Today in class we went through our module two study guides again today. We started on number twelve. We discussed that if you put energy in and get work out. We also learned that Kinetic Energy and Potential Energy equal the same in the beginning, middle and end. As something is thrown up the Kinetic Energy is at its highest and Potential Energy is at its highest when the ball is about ready to fall. We also discussed what simple machines do to help. We discussed that force has an advantage of distance. There are two types of simple machines are lever and incline plane. All simple machines are one of these two things. We also discussed what force fields are. We learned that they are any mass in the field space that experiences a force. It affects you and objects. We learned that even two markers have some type of magnetic attraction. As they get closer the attraction becomes stronger and as they move away it becomes weaker. We also talked about tides on earth that are caused mainly from the moon but the sun also has a small effect. They are the strongest when closest to the moon and weakest when far away from the moon. We also just need to know the definitions of Kepler’s Laws.
