Transcript Science_Review 9_Forms of Energy
Review 6 1. Energy - the ability to make things move or change. 2. Chemical Energy - the energy that objects have. It is stored in the food we eat. We use it to keep our bodies running. * Example: a car burns gasoline to move the engine.* Review 6 3. Energy Transformation - when energy changes from one type to another. Example: a doorbell changes an electrical current into sound.* 4. Mechanical Energy - the energy in moving objects. Review 6 5. Potential Energy – stored energy. An object’s potential to move because of its position and Earth’s gravity. 6. Kinetic Energy – energy of movement. It is cause by the mass and speed of a moving object. Review 6 7. Heat Energy – moves between things that are at different temperatures. 8. Solar Energy – a form of energy that combines the properties of light and heat from the sun. Review 6 9. Magnetism – the ability to attract certain metals, and to attract or repel other magnetic materials. 10. Attract – when two objects pull towards each other. 11. Repel – when two objects are pushed away from each other. Review 6 12. Electricity – the movement of negative charges from one place to another. 13. Electrons – negatively charged particles. 14. Current – movement of electrons through a conductor. *Example: wire* Review 6 15. Static Electricity – a charge that builds up when two things rub together. 16. Conductor – any material that allows electrical charges or heat to travel easily through it. 17. Insulators – do not let electricity or heat travel through them easily.
