In Unit 8 we learned about work and energy. The Law of conservation of Energy is that energy cannot be created or destroyed. It just changes forms and is conserved. We learned that there are two types of energy, Kinetic and Potential. Kinetic is the energy of motion which includes the units mass, gravitational force, and velocity. Potential energy is the Spring potential energy and can help you determine the distance that the string is stretched or depressed. The units of Potential Energy are spring constant (k), and the distance that the string is stretched or depressed. In this picture I took a picture of myself pulling back a sling shot. The equation that we could use to solve for is Spring Potential Energy because as I pull the spring back the harder it gets to pull. We could solve for how much work it will take to pull back a rock or an object that weighs a certain amount using this equation or finding the slope of the graph.
Cool. That really helps me understand it better.
ReplyDeleteGreat job. Thats a good example.
