This energy is used to move or lift things. For example, hammering a nail into wood.  ]]> 2023-02-09 21:42:16 UTC https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2475666180 4545872 https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2485412781 Sound energy is carried by sound waves, for example, your voice box vibrating to make sound. And another example is a speaker or radio. These things make sound, and we get that sound via sound waves. Also, sound can go through all states of matter. ]]> 2023-02-16 18:39:12 UTC https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2485412781 4545872 https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2485413327 Thermal energy is created when two or more molecules bump together and cause friction and make thermal energy.
Another example of thermal energy is a bowling kettle.]]> 2023-02-16 18:39:23 UTC https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2485413327 4545872 https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2485414390 2023-02-16 18:39:54 UTC https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2485414390 4545872 https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2485416813 Chemical energy is when energy is stored within the bonds of atoms. In other words, chemical reactions. For example, when we eat, we turn that food into energy. That is called chemical energy. ]]> 2023-02-16 18:41:58 UTC https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2485416813 4545872 https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2485417286 Electrical energy is a stream of negatively charged electrons that are used to charge/ power your electronics like your phone TV and computer.]]> 2023-02-16 18:42:22 UTC https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2485417286 4545872 https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2485449669 Light energy is energy carried by changed partials. All types of electromatic and radiations have energy. For example, charging electronics and powering lights.]]> 2023-02-16 19:02:14 UTC https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2485449669 https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2485463673 2023-02-16 19:12:55 UTC https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2485463673 https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2485465278 Energy is the ability to work. The ability to do anything is accomplished by using energy. For example, walking a dog requires you and your dog to have eaten so that you can turn the food into chemical energy and then into mechanical energy so you can walk. Another example is when we drop a ball. That is the ability to work and that's energy. ]]> 2023-02-16 19:14:09 UTC https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2485465278 4545872 https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2490381327 Yes! Energy can change in many ways. Energy can change forms. This is called energy transformation. An example of energy transformation is when chemical becomes mechanical. Or energy can change its location. This is called energy transfer. An example of energy transfer is when thermal energy goes from the sun to the ground.  ]]> 2023-02-21 23:20:46 UTC https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2490381327 4545872 https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2491503439 No! Energy can't be created or destroyed because of the Law of Conservation of Energy. This law states that energy can't be created or destroyed. However, energy can change. This law applies to energy transfer and energy transformation. When these processes happen sometimes there are some waste energies. That waste energy can't just be destroyed. So, it forms other molecules. For example, in photosynthesis there is oxygen as waste. That oxygen is something we breath in and something we use. ]]> 2023-02-22 17:39:53 UTC https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2491503439 4545872 https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2491504713 Yes! If you think of a campfire, it is taking on different types of energy. For example, it takes oxygen to fuel the fire. It then takes that oxygen to create thermal and light energy at once. Another example is Roket it gives of thermal, light, and sound energy.]]> 2023-02-22 17:40:55 UTC https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2491504713 4545872 https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2491505431 Energy flows through a system in many ways. For example, a flow system can be our Phet lab. We had a sun, solar panels and a fan. The way this flow chart worked is that the sun gives off light energy. Then that light energy transfer on to the solar panel. The solar panel then transformed that light energy into electrical energy. This energy was then transformed into mechanical energy which was the fan spinning.

Some systems produce waste energy. Waste energy is energy that was not used in the system. That waste energy does not just disappear. This is because of the Law of Conservation of energy. For example, photosynthesis is a flow system that has a byproduct or waste (oxygen). This oxygen is something we use for our ability to work and for our flow system.  ]]> 2023-02-22 17:41:31 UTC https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2491505431 4545872 https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2491506219 Energy transfer is when energy moves from one object to another. For example, Newton's cradle is a contraption that transfers energy from one ball to another. Another good example is bumper cars, when you bump into someone you transfer your energy to the other car. ]]> 2023-02-22 17:42:08 UTC https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2491506219 4545872 https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2491507381 Energy transformation is when energy changes from one form to another. For example, solar panels. Solar takes light energy and creates electrical energy. Another example is in your car, chemical fuel that is gas (petroleum) gets converted into mechanical energy. ]]> 2023-02-22 17:42:57 UTC https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2491507381 4545872 https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2491508270 The "Law of Conservation of Energy" is similar to the "Law of conservation of Mass" the law says that energy cannot be created or destroyed. For example when you eat food it turns into chemical energy, and then that energy gets turns into Mechanical energy. Another example is waste energy. For example, in the process of photosynthesis the waste of oxygen is not just wasted and diapered. That oxygen is used by other things for example humans. ]]> 2023-02-22 17:43:40 UTC https://padlet.com/4545872/szwu6otqu5xo11dm/wish/2491508270
