Energy Study Guide Answers E1- I can list the major types of energy. 1) Sound, Electric, Mechanical, Nuclear, Heat, Solar, Chemical 2) Sound- Vibrations through matter. Electric- Traveling electrons. Mechanical- Energy of objects due to position and/or movement. Nuclear- Energy released from the nuclei of radioactive materials. Heat- Energy used to cook or heat things. Solar- Light Chemical- Energy stored in the bonds of materials. 3) Sound- Mr. Bowen Talking Electric- Power lines Mechanical- A baseball being thrown Nuclear- Nuclear power plant Heat- A fire Solar- Sun Chemical- Doritos E2- I can explain how the arrangement of objects effects potential energy. 4) Raise an object higher off the floor to increase GPE. 5) Decrease the distance an object is stretched to decrease EPE. E3- I can define potential and kinetic energy. 6) Gravitational potential energy is energy associated with the position of an object in relation to the ground. A ball held out of a window. 7) Elastic potential energy is energy stored in stretchy objects. Stretching a rubber band. 8) Kinetic energy is the energy of a moving object. A Frisbee being thrown. E4- I can describe heat movement. 9) Heat always travels from a warmer object to a cooler object. 10) Conduction is a mode of heat travel that occurs due to direct contact of atoms. It has to have matter in order to work. 11) Convection is a mode of heat travel that occurs in fluids (liquids and gases). Heat travels due to density differences between warmer and cooler fluids. Warm fluids are less dense and rise, cooler fluids are denser and sink. Only works with matter. 12) Radiation is a mode of heat travel that occurs with or without matter. This is how heat from the Sun heats the Earth. E5- I can explain the relationship between temperature and kinetic energy. 13) Temperature is the measure of the average kinetic energy of all particles in an object. Kinetic energy is the energy of motion. They are related because temperature is a measure of kinetic energy. E6- I can explain how energy transforms from one type to another. 14) Solar energy Chemical energy Chemical energy Kinetic energy Sun Plant Dog Dog running 15) Solar energy Chemical energy Chemical energy Chemical energy Kinetic energy Sun Plant Pig Mr. Bowen Running 16) When a ball hits the floor kinetic energy is converted into sound, heat and some more kinetic energy. E7- I can explain and apply the law of conservation of energy. 17) Energy cannot be created or destroyed. 18) When the ball is dropped the potential energy it started with converts into kinetic energy as it falls. When it hits the floor it converts some of that original energy into sound energy, heat energy, and more kinetic energy to bounce back up. Since some of the energy went to other types of energy and not all to kinetic energy, the ball will not bounce back to its original release height. E8- I can investigate how the relationships among the energy transferred, type of material, amount of material, and change in kinetic energy by use of temperature. 19) Container B will have a higher temperature than Container A, because the higher amount of objects to collide of the Container B will produce more friction than the lower amount of objects in Container A. The more friction there is the more heat energy there is and the more the particles move with kinetic energy.
