Where is the spring potential energy at a maximum?
The initial situation is defined when the spring and block are compressed, and the final situation is defined to be when the block moves back through the equilibrium point. For a spring, the potential energy is maximal when the spring is compressed and the kinetic energy is maximal when the mass passes equilibrium.
How do springs work physics?
A spring is an elastic object that stores mechanical energy. Springs are typically made of spring steel. A torsion spring is a spring that works by twisting; when it is twisted about its axis by an angle, it produces a torque proportional to the angle.
What is spring and spring work?
When a spring pulls something, or pushes something, over a distance x, it does work 2 work = 1/2 * k * x. If a spring is compressed (or stretched) it stores energy equal to the work performed to compress (or stretch) it. We might call this spring potential energy.
How do you calculate the work done by a spring?
Let the spring be stretched through a small distance d x dx dx. Then work done in stretching the spring through a distance d x dx dx is d W = F d x , dW=Fdx, dW=Fdx, where F is the force applied to stretch the spring.
When a spring is stretched or compressed it has?
potential energy
A spring has potential energy, both when it is compressed or stretched.
When the potential energy of a spring is minimum?
When a spring is at its natural length (i.e. neither stretched nor compressed), the potential energy of a spring will be minimum.
What does k mean in spring constant?
Direct link to nick46928’s post “K indicates the spring co…” K indicates the spring constant of that spring. It is just a constant that varies depending on the spring. A common exercise in an introductory physics lab is measuring the spring constant of a spring experimentally. Comment on nick46928’s post “K indicates the spring co…”
What is the spring constant of Young’s modulus of a material?
Young’s modulus can be defined at any strain, but where Hooke’s law is obeyed it is a constant. We can directly obtain the spring constant kkkk from the Young’s modulus of the material, the area AAAA over which the force is applied (since stress depends on the area) and nominal length of the material LLLL.
What happens to the mechanical energy when a spring is compressed?
As the spring becomes compressed and the mass slows down, its kinetic energy is transformed into elastic potential energy. As this transformation occurs, the total amount of mechanical energy is conserved. This very principle of energy conservation was explained in a previous chapter – the Energy chapter – of The Physics Classroom Tutorial.
How does the force of a spring depend on its length?
The force exerted by a spring on objects attached to its ends is proportional to the spring’s change in length away from its equilibrium length and is always directed towards its equilibrium position. Assume one end of a spring is fixed to a wall or ceiling and an object pulls or pushes on the other end.
