“INTRODUCTION TO ENERGY” WORKSHEET



INTRODUCTION TO ENERGYName_________________________________________ Date _______________ Part 1. The two basic types of energy Directions: Determine the best match between basic types of energy and the description provided. Put the correct letter in the blank. ______1. A skier at the top of the mountain(a) Kinetic Energy______2. Gasoline in a storage tank(b) Potential Energy______3. A race-car traveling at its maximum speed(c) Both forms of Energy______4. Water flowing from a waterfall before it hits the pond below______5. A spring in a pinball machine before it is releasedPart 2. Definitions of Energy.Directions: Write down the definition for each of the following terms.ENERGY:KINETIC ENERGY:POTENTIAL ENERGY:Part 3. Forms of Energy.Directions: Read each type of energy and its definition.Type of EnergyDefinitionChemical energyEnergy stored in the chemical bonds of molecules (ex. gasoline)Electrical energyEnergy that is carried by electrons usually through a wireKinetic energyMoving energy (ex. bicycle)Potential energyStored energy (ex. food)Sound EnergyVibrations of waves through a material (ex. Playing a guitar)Nuclear EnergyStored in the nucleus of an atom; released when the nucleus splits or combines (ex. Atomic bomb, nuclear fission used to produce electricity in power plants)Radiant/light energyEnergy that is transferred by rays, waves, or particles (ex. The sun, x-rays)Thermal energyEnergy associated with heat (ex. Melting ice cream)Part 4. Forms of Energy ContinuedDirections: Match the energy form(s) to the description provided. A few questions may have more than one answer. _____________1. Falling rocks from the top of a mountain(a) Kinetic_____________2. Release of energy from the Sun(b) Electrical_____________3. Food before it is eaten.(c) Thermal_____________4. Energy released from food after it is eaten (d) Radiant_____________5. The energy that runs a lamp(e) Chemical_____________6. Nuclear fission reactors(f) Nuclear_____________7. The rumble of thunder from a storm(g) Sound_____________8. Rubbing your hands together(h) Potential_____________9. Gasoline_____________10. BatteriesDirections: Energy can change from one type to another. This is called energy transformation. Using the types of energy listed above in the table, answer the following questions.571500036195001. In a computer monitor, _____________energy is changed to _____________ energy and sound energy.5943600223520002. When you burn wood in a campfire, _____________ energy ?is converted to _____________ and light energy. 5715000387985003. Through the process of photosynthesis, _____________ energy from the sun is changed to stored _____________ energy.5943600334645004. At a hydropower facility, the _____________ energy of flowing water can be used to spin a turbine and power a generator, creating _____________ energy.5. In a car, the _____________ energy in gasoline is burned to create heat energy, which is converted to _____________ energy.571500012319000Part 5. Transformation of EnergyDirections: Use the following forms of energy to fill in the table below: mechanical, electrical, heat, radiant, chemical, nuclear, and sound. The first one has been done for you.ORIGINAL ENERGY FORMFINAL ENERGY FORM1. Electric motorelectricalmechanical2. A battery that runs a moving toy3. A solar panel on the roof of a house4.
