Bow & Arrow: Potential energy stored in the limb or the cord string? - bow & arrow baloon shooting game
My son has a question about the forces of science. The question is whether the potential energy is in a branch cable or stored in a bow. The professor says the answer is "word of the bone, but my son has played with a bow and arrow, once observed that the elastic is at the top. So he wrote" Limbo "for an answer. Who is right?

Bow & Arrow Baloon Shooting Game Bow & Arrow: Potential Energy Stored In The Limb Or The Cord String?
3 comments:
The master is .... wrong. Potential energy in the legs before the arc stored, not the chain. The whole chain can deliver that stored energy to click the arrow. Here are the members of the Arc-appeal (as they are able) that the stored energy is transferred to the chain, then on the arrow. Regardless of whether a recurve bow, bow, compound bow, all business and deliver its potential energy in the same general method (the differences in the ends of the branches of the recurve bow recurve and "wheels" of the compound bow is to make two types of arch design better as the design of the arc in general).
Here are two websites for teachers to be considered:

Teachers should pay special attention to the section titled "Saving energy in the arc in the first site.
His son was right. I wonder if the teacher thought to the leg and arm stretches the back arrow.
It is a great satisfaction and / or disappointment when one discovers that a teacher is wrong.
Your child will need a good chart, should the names of the top and the chain with a statement and the private sector shows talk with the teacher.

Potential energy is stored in the spring action of the leg. If the arrow is released, the restoring force exerted on the tip of the arrow to the tension of the rope, but the real potential energy is stored in the member countries.
