CHANGES IN ENERGY Q1. The image below shows a student before and after a bungee jump. The bungee cord has an unstretched length of 20 m. (a) For safety reasons, it is important that the bungee cord used
AP practice ch 7-8 Multiple Choice
AP practice ch 7-8 Multiple Choice 1. A spool of thread has an average radius of 1.00 cm. If the spool contains 62.8 m of thread, how many turns of thread are on the spool? "Average radius" allows us to
4.2. Visualize: Assess: Note that the climber does not touch the sides of the crevasse so there are no forces from the crevasse walls.
4.1. Solve: A force is basically a push or a pull on an object. There are five basic characteristics of forces. (i) A force has an agent that is the direct and immediate source of the push or pull. (ii)
law of conservation of energy energy
What happens when? 6.8A compare and contrast potential and kinetic energy 6.9 Law of Conservation of energy states that energy can neither be created nor destroyed. How does it work? Explanation If you
