Anyone know about kinetic energy?
My thrid grader had to do a science project. His project was a balloon hovercraft. We had no problem making it and getting it to work. The problem we are having is he has to explain how kinetic energy makes it work. I looked up kinetic energy and it says it is the energy of motion. So is the air coming out the bottom and making the hovercraft move the kinetic energy? I don't want to help him get it wrong.

I would think the air is the potential energy (energy stored in an object)..the moving of the hovercraft is the kinetic energy (energy of motion).

Re: Anyone know about kinetic energy?
Kinetic Energy: A gymnast on the beam has kineatic energy. The movements and flips that she does show the energy that is being displayed while she is moving. When you are running, walking, or jumping, your body is exhibiting kinetic energy.
-----------------
Kinetic energy is the energy of motion. Kinetic energy is measured by how much is work done to put an object in motion or to rest.
----------------
Kinetic Energy exists whenever an object which has mass is in motion with some velocity. Everything you see moving about has kinetic energy.

He ended up getting an A on the project and presentation. If it were not for you I'm not sure what he would have received. Thanks again. Kelly
