Energy Conservation and Transformation What type of energy

Energy Conservation and Transformation

What type of energy do we see on a roller coaster? Potential and Kinetic

Does the energy stay in one form? No!

Where does my energy to play sports come from? Energy doesn’t just “appear” it comes from something or some other form

Energy conversion Energy cannot be made Energy cannot be destroyed or “used up” Energy can just change from one form to another. Kinetic -> Potential -> Kinetic

Law of Conservation of Energy cannot be created or destroyed, only changed in form. https: //www. youtube. com/watch? v=8 GLt. FNai. MH 8

Are they using up energy? No- just converting it from one form to another

So, where does my energy to play sports come from? I get my kinetic energy from potential energy I have stored- from the chemical energy (food) that I ate.

What can I convert electrical energy into? Heat energy (in a toaster) Sound energy (in a radio) Light energy (in a bulb) Mechanical energy (on a ride)

Electrical energy goes into the hairdryer, what kind of energy is it changed into?

Nuclear Power Plant Nuclear E -> thermal E -> mechanical E-> electrical E

Energy can change forms

Activity 1. Sort the cards as a group 2. Write out the energy transformation seen for each object or action

kinetic (wind) -> mechanical (blades spinning) -> electrical Chemical -> thermal/light/sound Chemical (batteries) -> electrical -> light/heat (bulb) Mechanical (legs)-> mechanical (wheels) Electrical (plug) -> radiant (microwaves)-> thermal (heat) chemical
