The Research Experience for Teachers Program http://www.cs.appstate.edu/ret βConservation of Energy with Toysβ Summary: In this activity students will use image processing tools to study the motion of a spring-loaded toy. This will study the connections between elastic potential energy, gravitational potential energy, and kinetic energy. Elastic Potential Energy ππΈ = 1 ππ₯ 2 2 Acceleration π£π = π£π + ππ‘ 1 2 Gravitational Potential Energy ππΈ = ππβ Kinetic Energy πΎπΈ = ππ£ 2 β’ β’ β’ β’ β’ How can elastic potential energy be calculated? How can gravitational potential energy be calculated? Explain the Law of Conservation of Energy. What do you predict will happen when additional mass is added to the toy? What should be true about the kinetic energy of the toy just before hitting the ground when it is compared to the original elastic potential energy, according to the Law of Conservation of Energy?
