This Concept Map, created with IHMC CmapTools, has information related to: Energy concept map for students, Chemical Potential Energy definition Energy stored in fuels; released through chemical processes, Potential Energy includes Chemical Potential Energy, ENERGY measured in Joules (J), Gravitational Potential Energy can be illustrated by A 60kg man standing at the edge of a 20m high cliff will have a potential energy of 60 * 10 * 20 = 12000 J, ENERGY governed by Law of conservation of energy, ENERGY different types Heat Energy, Heat Energy definition Energy that flows from a refgion of higher to lower temperature, Energy cannot be created or destroyed; it can only be converted from one form to another illustrated by energy conversion examples A diver leaps off the board which is a certain height above the swimming pool. Assume negligible air resistance. When the diver is in mid-air, the energy conversion involved is Initial P.E = P.E in mid-air + K.E in mid-air, ENERGY different types Potential Energy, Kinetic Energy can be illustrated by A 60kg man running at a speed of 10 m/s will have a kinetic energy of 1/2 * 60 * 10 * 10 = 3000 J, Gravitational Potential Energy is calculated using Mass (kg) * Gravitational Force (N) * Height (m), Potential Energy includes Gravitational Potential Energy, Kinetic Energy is calculated using 1/2 * Mass (kg) * Velocity (m/s) * velocity (m/s), Power (W) * Time (s) can be illustrated by A 70W fan is turned on for 1 minute will consume an electrical energy of 70 * 60 = 4200 J, Potential Energy includes Elastic Potential Energy, Law of conservation of energy states that Energy cannot be created or destroyed; it can only be converted from one form to another, ENERGY different types Light Energy, ENERGY different types Kinetic Energy, A diver leaps off the board which is a certain height above the swimming pool. Assume negligible air resistance. When the diver is in mid-air, the energy conversion involved is Initial P.E = P.E in mid-air + K.E in mid-air a mathematical example A 60kg diver at an initial height of 5m leaps off the board to fall freely into the water. When he reaches a height of 1m above the water, calculate his velocity. Assume negligible air resistance. Initial P.E = P.E at 1m + K.E at 1m (60)*(10)*(5) = (60 * 10 * 1) + (1/2 * 60 * v * v) Therefore, v = (8.94) m/s, Light Energy definition Energy that enables us to see
