Physics Themed: Unit 12 "Rollercoaster Energy" 12 Energy Conservation of energy is the key feature of this short unit. Kinetic and gravitational potential energy and their sum, mechanical energy, are conserved and must be accounted for. You will learn about these energy concepts and how they apply to every day situations as well as coaster design. The math here is very, very simple: The challenge is understanding the concepts involved in various situations and how conservation of energy can give the student a framework to understand the relationships between mass, speed, height (elevation) and the energy an object possesses. The math here just helps you be an energy accountant and to balance your energy checkbook. The student will learn that you can solve some motion problems using a different approach from Nifty equations and you still get the same answer.
