Before the rubric, I included the results from our previous lab, which you must use to find the potential and kinetic energies for this lab. You wouldn't be wrong, but every object, moving or stationary, has energy. Explanation: . Discussion The activation energy is the minimum amount of energy needed for colliding species to react. By considering the playground swing, looking at diagrams, and using real-world pendulums, students understand how kinetic and potential energy relate within a system. The Work-Energy Theorem presents a way of dealing with kinematic quantities in me-chanics without regard for vector direction. does anyone know a quick way to do lab reports i absolutely despise them and they're the only thing i skip but I need to complete the whole thing. This report must be typed, and any diagrams, figures, or tables should be embedded into the document. Friction. Students learn about the conservation of energy and the impact of friction as they use a roller coaster track to collect position data and then calculate velocity and energy data.

Unofficial Student-led Edgenuity Subreddit Think about what you already know about energy. You always get 8 slices, but some of those slices might be cheese, while others might be pepperoni… 3. The temperature is the average kinetic energy per molecule of a substance. E2020 recently changed its name to Edgenuity, however alot of the answers for subjects stayed the same. The momentum and kinetic energy of Glider 2 can be computed from the velocity measured, and from the mass of Glider 2. However, in the event of a phase change (water melts at 273K), the heat of fusion or vaporization must be added to the total energy cost.
