Energy Foldable Types Forms and Energy Transformations 1
Energy Foldable Types, Forms and Energy Transformations
1. Energy §The ability to do work or cause a change.
§ There are 2 types of kinetic Energy: ___________________. and potential
A. Kinetic Energy § Energy related to the motion of an object, the object is moving. § ALSO KNOW AS MECHANICAL ENERGY
Examples of Kinetic Energy Examples: § Shooting a basketball § Skateboard rolling down the hill
faster § 1. The _______ something is moving the more kinetic energy it has.
mass § 2. The more _____ a moving object has, the more kinetic energy it has.
B. Potential Energy §The energy of position, stored energy, the object is not moving.
Examples: § A stretched rubber band § Or a compressed spring
2 Kinds of Potential Energy § 1. Elastic potential energy – stored energy as a result of deformation of an elastic object. § 2. Gravitational potential energystored energy that depends on 3 things: the mass, the height, and the acceleration of an object.
§ 2. One of the most familiar forms of energy is thermal energy, which _____ you can sense as heat ______.
§ 3. All matter is made of particles that small ______ are constantly in motion _____.
§ 4. If thermal energy is added to matter, the particles move _____, and the faster warmer matter feels _____.
§ 5. If thermal energy is lost, the particles move more _____, and slowly the matter feels colder _____.
Chemical energy § 6. ______ is transformed to other forms of energy during a chemical reaction.
Examples of Chemical Energy: § Food § Batteries
Examples of Chemical Energy: § Candles § Photosynthesis
§ 7. A moving electrical charge produces electricity ______.
§ 8. The energy of these moving particles is electrical energy. ______
§ 9. Electrical energy becomes useful when it is ______ transformed into other forms of energy.
Examples of Electrical Energy § Electrical Outlets § Electrical Wiring
Sound energy is § 10. _______ caused by an object’s vibrations.
§ 11. Vibrations that produce sound are transmitted through the air _______.
Examples of Sound Energy § Tuning Fork § Guitar String
§ 12. A familiar form of electromagnetic energy light is ______ energy. (Also known as radiant energy)
microwaves § 13. X-rays, _____, TV signals radio and _____ and ultraviolet rays are also forms of electromagnetic energy.
§ 14. When electromagnetic energy interacts with matter it can produce physical ______ or chemical changes. ______
§ Cooking in a Microwave § Getting a sunburn
§ 15. _______ Nuclear energy is energy that can be caused by changes in the nucleus of an atom.
§ 16. Nuclear energy is used to produce electricity in _____ Nuclear power plants _________.
Examples of Nuclear Energy § Sun § Nuclear fusion/fission
17. Energy Transformation §When any form of energy changes into another form of energy.
Example of Energy Transformation: § A light bulb can transform electrical energy into thermal energy and light (electromagnetic energy)
Example of Energy Transformation: § A candle burning transforms chemical energy in candle wax to thermal and electromagnetic energy, (heat and light)
18. Law of Conservation of Energy §Energy is neither created nor destroyed, it simply just changes form.
