This last week of Physics, we have started the Unit about energy. Energy can be measured in Newton meters, or Joules. A joule is equal to: (kg x m/s^2 x m). By the law of conservation of energy, energy cannot be created nor destroyed; it only changed form. This is just like how momentum is conserved. However, this is only true in a 100% efficient system. For example, energy from the wall outlet runs through my lamp in the form of electricity. This energy changes form as it enters the lightbulb as light. As the light continues to emit, this energy is released into the atmosphere as heat, and so forth.
awesome, jesus. I needed you this morning so you could help me. thanks for the help prick. see you in parsons.
ReplyDeleteGood example of the law of conservation of energy Jesus.
ReplyDeleteSup, I see you have a picture of a light, nice, nice. I like the equations. Sorry for the creeper comments.
ReplyDeletewooow that's a super bright light, i have one of those in my room too lol. good physics connection
