In what two ways can you increase the elastic potential energy of a spring?
79403
Increase it's length and wind it tighter.

Stronger, more flexible, light weight

Try a divining rod.  No one can explain how they word scientifically, but there are people (mostly old, rural folk) who can quite successfully use it to find a good spring.  My dad has been pretty successful (or lucky according to some people) doing it.

So the first one can be solved easily using the energy method. Potential energy = mgh = 2*9.81*6\nKenetic energy  = 1/2mv^2 = 1/2*2 * v^2\nBecause there is no friction Potential Energy = Kenetic Energy:\n\n2(9.81)(6)=1/2(2)(v^2) \n\nNow you just need to solve for v, using your calculator or head.\n\nFor the second one you have to account for the amount of energy lost from friction. So, instead of KE=PE you get:\n\nKenetic Energy = Potential Energy - Energy lost by Friction\n1/2*m*v^2 = m*g*h - Friction energy \n\nSo you can do some algebra and\nm*g*h - 1/2*m*v^2 = Energy lost by friction \n\n\nThree is impossible without more information. You can't solve for u with just m, theta, and work. You need some information about the height, or the length of the ramp, or end velocity. Just think about it, you could have a ramp 100ft tall with little friction, or you could have one 1 ft tall with lots of friction. The work done would be the same even if you kept the masses and theta the same.

read stretching scientifically.... you might be able to download it\nmichael\nwww.bandconsulting.com

Simple higher the pressure more will be the bounce.

Imagine the stretching of the surface of the drum as the stretching of a spring. use hooke's law to do calculation. u will need to know about the strength of material and etc. very very very complicated

This is letting spring energy = gravitational potential energy.\n\nkx²/2 = mgh→ k = 2mgh/x² = 2*1*9.8*.6/.02² = 29400 N/m

It doesn't matter...you require the same kinetic energy to climb one or two at a time....and you gain the same potential energy just by increasing your height.\n\nBy swinging your arms you would not use less energy because you would be required to USE energy to maintain the motion....thus cancelling out the energy gained by momentum.

how does it bounce without springs?

a) stretching - the objects "necks" or thins down\n\nb) compression - the objects "bellows" or gets fatter

There is a classic experiment in Physics where you suspend a ball on a spring balance and immerse it in a beaker of water sitting an a scale. As the ball enters the water the spring balance reading reduces and the scale reading goes up correspondingly. \nThe water is like the atmosphere. After the ball is immersed the scale does not change in value even if you let the ball go to the bottom of the beaker. The ball is like the plane and the bottom of the beaker like the earth.\nThe only way to change the weight of the earth (the beaker of water) is to bring something in from outer space (the ball) but if that thing already exists on earth it is already included in the weight of the earth.\nSimilarly if you could get all your planes far enough into outer space you could conceiveably lighten the earth.

Please use springs, or rubber bands.

A spring can be made of many different materials, it is usually of higher carbon steels heated and then quenched at a proper rate to give you the spring constant that you want.

If you have a piece of wire and you increase its mechanical energy, for example by winding it into a spring and then compressing that spring, you can wonder what happens to that energy when the spring is dissolved in acid.\n\nWhen the energy is stored in the spring, it is because atoms have been pushed to a place which is away from their natural lowest-energy position.  You could say that by squeezing the spring, you are pushing the nuclei in the metal coil to be closer than they naturally want to be.  Because they are in a higher energy configuration than natural unstressed metal, when they are separated by the action of the acid, the atoms end up with more energy than they do in the unstressed case.  This additional energy manifests itself as heat.\n\nSo, in summary, if you took two identical springs, compressed one of them and left the other one relaxed, and dissolved them in identical acid baths, the acid bath which holds the stressed spring would end up hotter as the energy formerly stored in the spring is released as heat.
