Types of Energy BLACKOUT Name:Key 1.) What is energy? Describe where energy can be found. Energy is the ability to do work or cause change to happen. Energy can be found everywherewhether potential or kinetic. 2.) What is kinetic energy? Give/draw one example. 4.) What is electrical energy? Give/draw one example. Electrical energy is where electrical charges (excited electrons) move through wires and other conductors. An example of electrical energy is a wall socket. 5.) What is light energy? Give/draw one example. Light energy is moving photons or electromagnetic energy that we can see. An example would be the sun’s light. 8.) What is chemical potential energy? Give/draw one example. Chemical potential energy is energy that is stored in chemical bonds between atoms. One example would be in the food that we eat. 9.) What is nuclear energy? Give/draw one example. Nuclear energy is energy found in the center or nucleus of an atom. It is released when we split the nuclei of atoms or fuse the nuclei of atoms. An example would be a nuclear power plant. 12.)Describe what the Law of Conservation of Energy states. The Law of Conservation of Energy states that energy cannot be created or destroyed. The energy transforms from one form to another. The amount of energy you started with is 13.)Explain an example of L.O.C.O.E. that we can find in the world around us. An example of the L.O.C.O.E is when a bowling ball hits pins and slows down. The energy is still present, just changed. No energy is created or destroyed. Kinetic energy is energy that is moving energy or energy that is being used. An example would be a person running. 2.) What is thermal energy? Give/draw one example. Thermal energy is the movement of particles that creates heat. An example of thermal energy is rubbing your hands together. 6.) What is mechanical energy? Give/draw one example. Mechanical energy is the movement from one place to another due to motion or the position of an object due to motion. An example would be a bus moving from stop to stop. 10.) What is gravitational potential energy? Give/draw one example. Gravitational potential energy is energy due to an object’s position above the Earth’s surface and its potential to be pulled by gravity. An example would be raindrops. 14.) What happens to energy if it is neither created or destroyed? Energy is changed from one form to another. 3.) What is sound energy? Give/draw one example. Sound energy is kinetic energy as vibrations travel through air and other objects in the form of a compressional wave. An example of sound energy is a microphone. 7.) What is potential energy? Give/draw one example. Potential energy is stored energy or energy that has not been used yet. An example would be an acorn hanging from a tree. 11.) What is elastic potential energy? Give/draw one example. Elastic potential energy is the energy due to stretching or compression of an object. An example is a bow that is stretched and ready to release. 16.) All forms of energy are considered potential. How is that possible? All forms of energy could be considered potential at one time or another if the energy is stored or is not being used. the amount of energy you end with. 17.) What is an energy transformation? An energy transformation is a change in energy forms. 21.) What is an independent variable? The independent variable is the manipulated variable; it is the one that the scientist changes. 25.) What is a constant variable? A constant are all the other variables that you should strive to keep the same in an experiment. 18.) Describe the following energy conversion: Turning on a lamp/light The main energy conversion that happens is electrical to light (radiant). 19.) Describe the following energy conversion: Toasting a piece of bread 22.) What is a testable question? What is the correct format? 23.) What is a dependent variable? A testable question is one that can be tested through experimentation. The correct format most often used is the “How does this affect that?” format. 26.) What is an observation? An observation is a statement based on something you noticed using your five senses. What is an inference? An inference is a conclusion that you reach based on an observation. The main conversion that happens is electrical to thermal. The dependent variable is the variable that is a result of the independent. It is what you measure as a result of the variable that you change in an experiment. 27.) Using the diagram below, label where the roller coaster has the highest amount of potential energy. A 20.) Describe the following energy conversion: Hitting a drum The main conversion is mechanical to sound. 24.) What is a hypothesis? How should a hypothesis be written? A hypothesis is a statement about what you think will be the result of your experiment. A hypothesis should be written in a “If, then, because” statement. 28.) Using the diagram below, label where the roller coaster has the highest amount of kinetic energy. B
