Science Energy Study Guide Flashcards
This will help you study about types of energy, kinetic and potential energy, law of conservation of energy, Sankey diagrams, and energy plants and their locations.
Give an example of sound energy.
Music
Give an example of light (electromagnetic) energy.
Lightbulb
Give an example of nuclear energy.
Nuclear power plant
Give an example of magnetic energy.
A fridge magnet
Give an example of chemical energy.
Plants
Give an example of gravitational energy.
Cyclist at the top of a hill
Give an example of elastic energy.
Trampoline
Give an example of mechanical energy.
Moving train
Give an example of thermal energy.
Hot air balloon
Give an example of electrical energy.
Computer
Choose a type of energy and explain how it could be considered as both potential and kinetic energy.
Gravitational can be considered as both because an object above the ground might be in motion and have the potential to move more as well.
Choose a type of POTENTIAL energy and explain how Increasing the distance between two objects affects the amount of energy they have stored. (INCLUDE evidence from labs)
The magnetic energy increases when there’s a smaller distance. In one of our labs, when the 2 magnets were close together, there was more force meaning that there was more energy.
Define the Law of Conservation of Energy.
Energy cannot be created or destroyed, only transferred or transformed.
Give an example of an energy transfer process and explain how it supports the law.
In a hairdryer, the electrical energy turns into thermal and sound energy. The sound energy is waste energy. All of this shows how the electrical energy was not destroyed, but instead transformed into thermal and sound energy.
Draw a model to support your answer.
Input- electrical
Useful energy- Thermal
Wasted energy- Sound energy
(Remember which places these are supposed to go in on the Sankey diagram, if you need to see then just look at the study guide.)
