Does a series of springs behave like one equivalent spring while oscillating?

A series of $n$ springs, where the $i$-th spring has spring constant $k_i$, is said to be equivalent to one single spring with spring constant $K$ if $1/K = \sum_{i=1}^n 1/k_i$. But what does ...

Hooke force and first Newton principle, how apply it

I have a question that maybe for this site is quite trivial, so sorry at first! If I have a spring and a force F determines an elongation of it: the difference between the length after the application ...

Energy conservation and slowly letting a spring go back to equilibrium

Suppose I have a spring with one end attached to a wall and the other end attached to a piece of rope. Now imagine I pull on the rope and pull the spring outward. My hand expends energy and the spring ...

Understanding the relationship between the spring constant and the angular frequency

Suppose, I have a spring whose spring constant is $k_s$, angular frequency is $\omega_s$, and the mass of the object attached at the end of the spring is $m_s$. So, will this be the relationship ...

Does the spring constant of a spring depend on the mass of the object attached?

Previously, I knew that the spring constant of a spring doesn't depend on the mass of the spring nor the mass of the object attached at the end of the spring. However, after doing this numerical today,...

The another answer for a question [closed]

The standard answer for this question is $\frac{2mgh}{(h-L)^2}$ and this is derived from conservation of energy. However, is there another answer to this problem? Since Kate just touches the surface ...

What is the reaction force to the spring force?

Suppose we have a spring suspended downwards and a mass of block M that is pulling that spring downwards. We have the W force (that is m x g) acting upon that mass of block M and we have the spring ...

Hooke's Law and Period of Oscillation when the spring has non negligible mass [closed]

If a block of mass $M$ is attached to a spring of mass $m$ and its force constant is $k$, if the system oscillates horizontally on a frictionless ground. We could derive the period of the oscillation ...

Is there any energy loss if two blocks collide with a spring in between?

If two blocks collide with a spring in between, at the moment when the spring reaches max compression is any energy lost? One can look at it as an inelastic collision since the two blocks would be ...

Simple Harmonic Motion vs other analogous problems

I've reading about Simple harmonic motion, and it is said that SHM occurs only when there is force $F \propto -kx$. This is true for spring-mass systems. However, in systems like the Pendulum, we have ...

Two cars tied with a spring [closed]

A spring of spring constant $k$ is tied with two cars of masses $m_1$ and $m_2$ with a rope. As a result, the spring is compressed by $x$ meters. Initially, assume that they are at rest. Suddenly, the ...

Does spring exert not force while in slack condition?

Consider a block of mass $m$ hunged by a spring of spring constant $k$. Let it be in equilibrium position where $mg=kx$. Now it is given a sudden impulse in upward direction so that it starts moving ...

How do you find the average velocity of a damping spring mass system?

I did some research and found out that it can be assumed that: $\mathrm{Average \ Velocity} = 0.5 \ × \ V_{max} = 0.5 × \mathrm{angular \ frequency} \times\mathrm{maximum \ displacement}$ But which ...

Maximum extension in spring

Suppose a mass $m$ is attached to a spring. Now if the mass is released, the tension will be the restoring force of the spring and since the mass is neither going up nor going down, we have $kx=mg$ or ...

Vertical ideal spring, streched by weight, different results working with forces and energy [duplicate]

Imagine we have a vertical spring with constant $k$ and load on it (like a weighing machine) a mass $m$. Initially, the energy of the system is $0$, since the spring it's on it's original position and ...
