Potential and Kinetic Energy doesn’t just “appear” it comes from something or some other form Energy cannot be made Energy cannot be destroyed or “used up” Energy can just change from one form to another. Kinetic -> Potential -> Kinetic Energy cannot be created or destroyed, only changed in form. https://www.youtube.com/watch?v=8GLtFNaiMH8 No- just converting it from one form to another I get my kinetic energy from potential energy I have stored- from the food that I ate. Heat energy (in a toaster) Sound energy (in a radio) Light energy (in a bulb) Mechanical energy (on a ride) Energy is the ability to make things do work Energy has no mass and no volume Energy can be found in 7 different forms Energy due to the position or motion of an object Energy of vibrating air molecules https://www.youtube.com/watch?v=Ude8pPjawKI https://www.youtube.com/watch?v=ynqzeIYA7Iw The energy used to hold atoms in a molecule together, such as in food or fuel. Chemical bonds are broken during a chemical reaction (burning, rusting, digestion) What organelle in our cells helps break the chemical bonds of food molecules so we can have energy? Mitochondria Muscles tissue The movement of electrons through matter. Electricity is a form of electrical energy. Energy carried by light, x-rays, microwaves Visible light is a form of electromagnetic energy. Each color of light (Roy G Biv) represents a different amount of electromagnetic energy. Increasing Energy The vibration of particles of matter. More vibrations = more heat energy (hotter) Fewer vibrations = less heat energy (cooler) The energy that holds protons and neutrons together in the nucleus of an atom The nucleus of an atom is the source of nuclear energy. When the nucleus splits (fission), nuclear energy is released in the form of heat energy and light energy. Nuclear energy is also released when nuclei collide at high speeds and join (fusion). Nuclear E -> thermal E -> mechanical E-> electrical E The sun’s energy is produced from a nuclear fusion reaction in which hydrogen nuclei fuse to form helium nuclei.
