Overview<\/h3>\n

Energy provides the capacity of matter to do work.\u00a0 Without it, there would be no chemical reactions or physical reactions and matter would be inert.\u00a0 It exists in forms such as potential energy and kinetic energy, and can be measured as heat.<\/p>\n

Potential Energy<\/h3>\n

Potential energy is stored energy.\u00a0 Water behind a dam is stored as potential energy.\u00a0 Also, if a ball is located 5 feet above the ground, it has more potential energy than a ball that is at ground level.\u00a0 Gasoline carries potential energy to take part in chemical reactions within the internal combustion engine of an automobile. If an arrow is set on a bow and the bow is bent, the bent bow has potential energy stored.<\/p>\n\n\n\n

Figure 1:\u00a0 As the archer draws the bow, the bow changes shape.\u00a0 The tension causes potential energy, which will be released as kinetic energy with the moving arrow.<\/p>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Kinetic Energy<\/h3>\n

Kinetic energy is the energy of any moving object.\u00a0 If the water behind the dam is released, the energy from the moving water will generate electricity from turbines.\u00a0 The ball located 5 feet above the ground will bounce higher and longer than one at ground level, as its potential energy is released.\u00a0 Similarly, the gasoline will combine with oxygen inside the internal combustion engine, allowing it to enter into chemical reactions that release its potential energy as it burns.\u00a0 As the vehicle moves, it carries kinetic energy.\u00a0 If a drawn bow is released, the nocked arrow will move through the air, converting potential energy to kinetic energy.<\/p>\n\n\n\n

Figure 2:\u00a0 The kinetic energy generated by the moving water in this waterfall could be harnessed to drive turbines and produce hydroelectric power.<\/p>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Heat<\/h3>\n

Energy can be measured as heat.\u00a0 There are 2 units that measure heat: the joule and the calorie.\u00a0 The joule is the SI unit, and 4.184 joules (or J), equal 1 calorie.\u00a0 That is the amount of energy it takes to bring 1 g of water by 1 degree Celsius.\u00a0 Heat is involved in many chemical reactions, as a catalyst or as a product of the chemical reaction.<\/p>\n\n\n\n

Figure 3:\u00a0 These balanced chemical reactions with two types of fuel and oxygen show how heat energy is released.<\/p>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Law of Conservation of Energy<\/h3>\n

The Law of Conservation of Energy (the First Law of Thermodynamics) states that energy cannot be created or destroyed, but it can be transformed from one form to another.\u00a0 When fuel is burned, the heat energy that is released is part of the reaction.\u00a0 Similarly, the potential energy carried by a ball at the top of the hill is transformed into kinetic energy as the ball rolls down the hill.<\/p>\n
