Shape of graph of energy in S.H.M
I'm confused to whether the graph of KE/PE of a simple harmonic motion system is sinusoidal or not
those are my best sketches but if unclear, the blue one is in a shape of a sine wave.
this question ...

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 ...

Why Doesn't the Amount of Work Determine the Elastic Potential Energy in Springs and Gravitational Potential Energy? [closed]
Why isn't the amount of work done on the spring the determining factor for the amount of elastic potential energy stored in a spring?
I learned that the change in potential energy is a result of the ...

Right displacement in spring potential energy [closed]
I have a doubt in general, the above problem is an example.
Here , the elastic string can be treated as a spring and we know the potential energy of a spring is $\frac{1}{2} k (x_f-x_i)^2$
So , ...

Why is energy not conserved in some cases? [closed]
I've got a lot of cases where the energy of the whole system is not conserved, that's probably because of some non conservative force.
One reason is that, the energy is transferred to heat, which is ...

Why does a spring have potential energy compared to a rod?
From what I understand, a solid body or rod should not add work to a system.
This is because these bodies internal forces are passed through touch:
If the action and reaction forces are applied at the ...

Spring attached to a block [closed]
CONCEPTUAL DOUBT: Consider an ideal spring of length $l$, one end of which is fastened to a wall and the other attached to a block. Take the spring as the system. Now as the block is elongated by a ...

Why do we only see the displacement of end points of spring while calculating it's potential energy?
I am a high school student and I am a little confused in understanding the spring potential energy formula. When we calculate the spring potential energy of a spring attached to a wall at one end and ...

Does any force on a spring make it oscillate?
If I push one end of a spring (while the other end is attached to a rigid support) with a force of F and over a distance of $x = F/k$, it is only after a the end of the spring has been displaced x ...

Help understanding a spring-mass system where mass is not attached
This is the scenario: We have a spring resting on a surface with no mass on it. Let the $y$ position of the top of the spring be $l_0$. When we put an object with some mass on top of the spring, the ...

Energy in simple harmonic motion ─ where is the kinetic energy stored, and where is the potential energy?
When a mass connected to a spring is in simple harmonic motion and somewhere between the mean and extreme positions the mass is cut from spring. Then instantaneously after cutting the mass will only ...

Do Ideal spring go on oscillating after given a push?
One end of an ideal spring is attached to the wall and other free end to a particle sized block (no friction). If a push is given to the block, will it go on oscillating about the equilibrium position?...

If I have a graph displaying the equation of elastic potential energy, why does the graph increase quadratically?
I was wondering why the graph is quadratic. If one could also link me to an external source to explain this, I would be just as grateful.
