Week 14 Blog, Due Sunday, December 09, 2012 by 11:00 PM
I hope you are all having a great year so far. I can't believe how fast it is going! Our most recent topic has been energy. So far, we have talked about Kinetic Energy (KE), Gravitational Potential Energy (GPE), and Mechanical Energy (ME). These, however, are not the only types of energy around us. For this week's blog, I want you to think about some other types of energy plus those we have spoke of. Some other types of energy include Solar Energy, Wind Energy, Energy in a spring, Thermal Energy, Chemical Energy, etc.. Look at the world around you and describe something in which an energy transformation is taking place. (An energy transformation is when one form of energy is turned into another form such as Solar Energy to Thermal Energy.) If you have any questions or problems posting your comments, please let me know BEFORE 4:00 pm on Sunday. As always, you can email your response if you have problems. Remember, in order to receive full credit, you must post an original comment PLUS comment on someone else's comment. Happy Blogging!

The only example i was able to think of was in the engine on a vehicle the fuel,which is chemical energy, gets transformed into mechanical energry.
ReplyDeleteThat's a good example
DeleteWind energy turned into electrical energy by those white wind thingies that power some electrical companies
ReplyDeleteI believe they are called wind mills KimG and great example! (:
DeletePerfect example, wind energy is something we always need!
DeleteLol, wind thingies! But good example(:
DeleteGreat example wind energy is a source we have always need. Btw the way like Alejandra said they are called wind mills lol
DeleteSolar energy is light and heat from the sun. Solar energy uses solar panels that can turn it either to mechanical energy or electrical energy. An example to of Solar to mechanical is Helios UAV in solar powered flight. An example of solar energy to electrical is using it to make rechargeable batteries.
ReplyDeletethats a good example for energy convertions
DeleteI agree with Ale it's a good example and well it's also a clean and efficient way to get electrical energy.
Deletegreat example rechargeable batteries are the best.

ReplyDeletewhen you plug in an electric stove its electrical energy converted to thermal energy.
ReplyDeleteExample would be a lightbulb because starts of as electrical energy when you turn the switch on and then turns to heat energy which then gives light energy in the bulb.
ReplyDeleteI think the heat and light energy come out at the same time but i like your example
Delete@Andres Basulto I think that first light energy is produced then is Heat Energy.
DeleteAnother example is a tv beacause it starts with electrical energy to light energy and sound energy and heat energy.
ReplyDeleteIt also gives a sort of wind energy that come outside of it for it not to over heat.
DeleteWe eat food is than it is digested which is chemical energy, the energy is used by our muscles to move the body, mechanical energy.
ReplyDeleteha! great example, the body has all the types of energy transformation if you look hard enough. even the solar. when skin absorbss light it is used to process vitamin d.(chemical energy?)
DeleteAn example would be when you connect a heater it goes from electrical energy into thermal energy because of the heat being released (:
ReplyDeleteThis is a really good example. It's also seen everyday during winter time for some people.
Deletenice example. and i've seen some older ones that when they are on, also give off little light energy because of the heat on the metal.
DeleteGood example! The same energy conversion would happen if you plug in a hair curler/straightener it blow dryer :D
Deletewhen a plant absorbs light to photosynthesize it is using solar energy to process carbon dioxide and water into chemical energy.
ReplyDeleteGreat example and I just want to say that the chemical energy that results from the plants photosynthesis contains oxygen and glucose.
DeleteWhen you start running after being in potential energy it turns into kinetic energy. Then after some time the kinetic energy turns into thermal energy which is why you start to feel a higher body temperature even though it's cold outside.
ReplyDeleteI like your example. I hope the temperature gets cooler outside.
DeleteAn example could be a toaster because it goes from electrical energy to thermal energy. This happens once the toaster is plugged in it begins to heat up.
ReplyDeleteSince its holiday time, an example would be christmas lights. When you plug them in, the electrical energy then turns into heat enery which causes light energy.
ReplyDeleteGreat Example! I forgot all about the lights on the tree!
Deleteelectrical to mechanical: would be turning on a blow-drier. The electricity goes inside the blow-drier and causes a fan inside to spin
ReplyDeletethats a good every day example!
DeleteRoller Coaster Rolling Down Hill is Potential Energy to Kinetic Energy. because it starts off with the potential to move but that action is put into place when it rolls.
ReplyDeleteChemical Energy from coal when it's burning in the Chimney becomes Heat & Light Energy!! :)
ReplyDeletespeakers converts energy too. It converts eletrical energy to sound energy.
ReplyDeleteGood example Toni^^
DeleteAn example that has always been given to me for this topic is a candle! Chemmical energy is used from the wax then we have the fire making heat energy and giving off light energy at the same time.
ReplyDeleteI've used this type of energy before:)
DeleteThe Hoover Dam has hydroelectrical energy used to power cites.
ReplyDeleteSo then it turns into electrical energy :)
DeleteAna Mendoza
That's a great example for electrical energy
DeleteElectrical Energy into Thermal Energy when heating something in a micorwave oven.
ReplyDeleteYhe three gorges dam in india or china creates hrdrolocity or electrical energy
ReplyDeleteYou forgot to mention where the transformation took place.
DeleteWhen you plug in a hair straightener and turn it on, energy turns from electrical to heat or thermal energy :)
ReplyDeleteGreat example Cindy! Same happens with the blow drier :)
Deleteelectrical energy to thermal energy when i blow-dry my hair after a shower!
ReplyDeleteAna Mendoza
Solar panels get thermal energy transforming it to mechanical, kinetic, and also potential energy
ReplyDeleteSteam engines use the thermal energy from heated water and convert it to mechanical energy.
ReplyDeletewind surfing uses wind energy to cause kinetic energy causing the board to move
ReplyDeleteIntresting didn't kno this
DeleteMittens that help keep your hands warm have molecules that activate when you touch them which activate heat which is Thermal Energy:)
ReplyDeletewhoa yeah that certainly is because it keeps hands warm and I need some xD
DeleteWhen water energy turns into mechanical energy when the water mill thingy turns and makes energy to power homes.
ReplyDeleteElectrical energy to kinetic energy is a fan.
ReplyDeleteI think it is wind energy though I am not certain
DeleteWind turbine turns wind energy into eletrical energy.
ReplyDeleteWhen a runner is about to run they are filled with potential energy which turns into kinetic energy once they begin moving
ReplyDeleteLighting a match goes from chemical to light and heat energy.
