How do you calculate the potential elastic energy in only one of the springs of a series? What about if they were connected in paralel? [duplicate]
Given the elastic constants of 2 springs (k1=125N/m, k2=200N/m), how can you calculate the ratio between the potential elastic energy stored in the first spring (k1) when it is grouped in series with ...

Elastic potential energy formula
From the Wikipedia page on elastic energy, we can find a bunch of formulas to describe it. For example, in the continuum section it talks about energy per unit of volume (density?):
$U=\dfrac{1}{2}C_{...

I have to figure out when someone comes to the first stop after bungee jumping. How would I do it?
This is the information I'm given.
John is attached to an elastic rope which is unstretched before John steps off the beam, and another end is fixed to a high beam. John then steps off the beam from ...

Do solids heat up on compression or extension? If so how?
Well, let's take the example of a compressible solid. We know that in order to compress a solid we need to apply a force "greater(and not really equal)" than the interatomic/intermolecular ...

Why is the mechanical energy lost whenever an object undergoes plastic deformation?
I have read here that "Mechanical energy is lost whenever an object undergoes plastic deformation."
Why is that? I mean the object would be changing its shape, and while it's changing its shape it ...

Calculating Elastic Potential Energy of a Stretched Sheet
Essentially, I'm trying to determine the amount of elastic potential energy stored in a thin, elastic sheet that has gone under some type of stretching (ex. A flag of stretchy fabric waving in the ...

Is energy stored in velcro considered Elastic Potential Energy in an inelastic Collision?
So just some background for the question, if two pucks with velcro on each side on very slippery ice with close to no friction collide, they stick together. Thus, the collision is inelastic.
However,...

Elastic potential energy in spring [closed]
We generate the formula from $W=Fs$, but why is it when we form the formula the $F$ becomes the average force applied, making the equation
$$W=(1/2)(0+F)x \, ?$$

When should gravitational potential energy be included in the law of conservation of energy
I have a problem that says:
A block of mass 0.249 kg is placed on top of a light, vertical spring
of force constant 4 975 N/m and pushed downward so that the spring is
compressed by 0.090 m. ...
