Energy Foldable Types, Forms and Energy Transformations

1. Energy  The ability to do work or cause a change.

 There are 2 types of Energy:____________ ___________________. kinetic 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

 1. The ______________ something is moving the more kinetic energy it has. faster

 2. The more _________ a moving object has, the more kinetic energy it has. mass

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.  1. Elastic potential energy – stored energy as a result of deformation of an elastic object.  2. Gravitational potential energy- stored 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 __________ energy, which you can sense as ___________. thermal heat

 3. All matter is made of small ___________ that are constantly in __________. particles motion

 4. If thermal energy is added to matter, the particles move _________, and the matter feels _________. faster warmer

 5. If thermal energy is lost, the particles move more _________, and the matter feels _________. slowly colder

 6. ___________ energy is transformed to other forms of energy during a chemical reaction. Chemical

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 ___________ energy. electrical

 9. Electrical energy becomes useful when it is ____________ into other forms of energy. transformed

Examples of Electrical Energy  Electrical Outlets  Electrical Wiring

 10. ______________ is caused by an object’s vibrations. Sound energy

 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 is ___________ energy. (Also known as radiant energy) light

 13. X-rays, __________, radio and _____ signals and ultraviolet rays are also forms of electromagnetic energy. microwaves TV

 14. When electromagnetic energy interacts with matter it can produce ___________ or ___________ changes. physical chemical

 Cooking in a Microwave  Getting a sunburn

 15. _____________ is energy that can be caused by changes in the nucleus of an atom. Nuclear energy

 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
