Force applied by hand, force applied by the spring and the corresponding work done
Consider a block of mass $m$ is attached to a massless spring of force constant $k$. If the spring is pulled by hand so that it stretches by an amount $x$, its potential energy increases from zero to $...

Spring potential energy, conversion
I have a physics problem in my book, where a spring is compressed and a ball is laying in the end of the spring. When the spring is released the ball will reach a certain speed. In the solution it ...

Strain energy stored in a bungee cord pulled at its midpoint [closed]
A bungee cord that behaves elastically has an unstressed length $L=.76$ m and a stiffness $k=140$ N/m. The cord is attached to two pegs, distance $b=.38$ m apart, and pulled at its midpoint by a force ...

How can we calculate entropy produced by plastic deformation in this example?
Suppose we have a massless spring of spring constant $k$ attached to a mass $m$ at equilibrium position $x_{0}$ at temperature $T$. The mass may oscillate in one dimension only for simplicity. We ...

What happens to the amplitude when a spring is compressed?
Say there's a spring lying on a horizontal table, with one end attached to a wall (say the left end) and it is in it's natural length. Now I compress the spring from the right end, and leave it. So ...

Problem with internal forces in spring following Hooke´s law
When looking at Hooke's law for the entire spring the force is $kx$.
But what happens when analyzing segments of the spring in order to look at the internal forces?
Imagine a spring of length $x$ that ...

Rotation of a mass attached to a spring
Consider a case where a ball or object of mass $m$ is attached to a spring that is hinged at one point. If the ball is given a velocity perpendicular to the spring, it does spiral motion due to ...

Does a block's velocity becomes zero when it hits a spring?
It says the velocity of the block becomes zero at the instant of maximum compression. But does it not go with a constant velocity as it's a smooth part? It should hit the spring and then oscillate for ...

Investigation Results of Damping of A Spring Showing Changing Phase Angle? Why?
In an experiment I've recorded the displacement of the spring over time, investigating underdamped simple harmonic motion.
Using pre-existing formulae the data should conform to a curve of the form

How does the centripetal force change when the radius changes?
The centripetal force for a constant radius is $m\frac{v^2}{r}$, but what if that radius is changing as you're spinning the object. Say a spring with a spring constant $k$ that is being spun with a ...

How does a soft compression coil on a frictionless surface react to a steady pull?
Could you explain the coil behaviour from the moment the pull begins until the entire coil starts to move?
There are explanations and videos about falling slinkys, but those are complicated by ...
