Energy Forms and Conversion ENERGY the ability to do work WORK is done when you use a force to cause motion WORK a force is moved through a distance “CLUES” – Types of Energy • • • • • • • • Kinetic Energy Gravitational Potential Energy Elastic Potential Energy Chemical Energy Thermal Energy Electrical Energy Nuclear Energy Radiant Energy Kinetic Energy • Energy of motion • Examples: KE = ½*M*V2 Gravitational Potential Energy • Stored energy that depends on an object’s height • Examples: GPE = M*g*H Thermal Energy • Energy of heat • Examples: Chemical Potential Energy • Stored energy in chemical bonds in compounds • When released, energy can do work • Examples: Elastic Potential Energy • Stored energy of a compressed or stretched object • Examples: Electrical Energy • Energy associated with electrical charges • Examples: Nuclear Energy • Energy stored within nucleus of an atom • Examples: Radiant Energy • Energy that travels through space in waves • Electromagnetic Spectrum • Examples: Sound • Form of kinetic energy • – movement of energy through substances in the form of waves Energy Conversion Cards • Front: • Form of Energy • Back: • 3 examples On either side include: • Picture of one of the examples Practice on Your Own • Energy Tracker: Jerome’s Story Conversion To change from one form to another Remember the 8 forms of energy… • A squirrel is walking along a telephone wire and then he falls off. • I stretch a rubber band, aim it at a student, and let it go. • An electric toaster is used to make toast. • A parked car begins to roll down the hill. • You jump up on a trampoline. • You plug in the microwave and turn it on. • A cloud is full of water. • Eventually, raindrops fall from the sky. • You flip on a light switch and the lights come on. • Sunlight makes a flower grow. • You eat a Power Bar before running the mile. • A coal-burning power plant produces electricity. • Person is standing on a diving board. • They jump off. • A Roller Coaster goes up and down hills. • Gasoline in a car is burned and the car moves. • You light the coals in a grill, then cook a hotdog. • A nuclear reactor is used to make electricity. • I plug in a fan and turn it on. • I plug in an electric blender and turn it on. • Then I eat the delicious milkshake. • The sun causes carrots to grow. • A bunny eats the carrots and hops around. • A basketball rebounds off the rim and hits the ground.
