What causes a spring to stretch?
In order to compress or stretch a spring, you have to do work. You must exert a force on the spring equal in magnitude to the force the spring exerts on you, but opposite in direction. The force you exert is in the direction of the displacement x from its equilibrium position, Fext = kx.
Does stretching or compressing the spring change the force Why or why not?
Work is force times distance, yes. But, the work done by stretching (compressing) a spring is not constant, since more force is required as the displacement increases.
Does a spring have more potential energy when stretched or compressed?
When you stretch or compress a spring you work against the restoring force of the spring. This work is stored as elastic potential energy in the spring. The more you stretch or compress the spring, the more work is done by you and more energy is stored.
What happens to a spring force if you stretch it more?
If too much force is applied, one may stretch or compress a spring beyond a certain point that its deformation will occur. On subsequent release of the stress, the spring will return to a permanently deformed shape which will be different from its original shape.
What kind of force is applied to a spring when it compresses?
When a spring is stretched or compressed, so that its length changes by an amount x from its equilibrium length, then it exerts a force F = -kx in a direction towards its equilibrium position. The force a spring exerts is a restoring force, it acts to restore the spring to its equilibrium length.
What do springs do?
A spring is an elastic object that stores mechanical energy and releases it when the opposing force is removed. If you need to apply force to create movement or hold something in place without the use of engines or other powered means, springs could be the answer.
How does the force supplied by a stretched spring compare to the distance it is stretched from equilibrium?
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.
What happens when a spring is compressed?
When you compress a spring, the potential energy is stored in the mechanical bonds between atoms, which you can think of as little springs. The reaction between a metal and an acid is exothermic, releasing energy to the solution and raising its temperature.
When you compress a spring What is the potential energy of the spring?
The potential energy stored in the spring is positive, when it is compressed and negative, when stretched.
What happens when we compress a spring?
When you compress a spring, the potential energy is stored in the mechanical bonds between atoms, which you can think of as little springs. The spring as a whole can’t decompress – until it breaks – but little chunks can decompress as they come off. Most of the stored energy goes into decompressing each small part.
When a spring is stretched the force changes the dash of the spring?
Explanation: when the spring is streched, the force change the, shape of the spring.
What happens when a spring is stretched or compressed?
When a spring is stretched or compressed, so that its length changes by an amount x from its equilibrium length, then it exerts a force F = -kx in a direction towards its equilibrium position. The force a spring exerts is a restoring force, it acts to restore the spring to its equilibrium length.
What happens to a spring when the spring constant is high?
The greater the spring constant, the stiffer the spring (the more difficult it is to stretch it or compress it). If a spring is stretched beyond its elastic limit, it will not return to its original shape and will remain deformed.
Do coil springs compress or expand when heated?
It could go either way. As Frank Heile notes, if it’s a coil spring then there’s a magnetic effect that tends to bunch the coils up, so the spring will tend to compress. On the other hand, the spring has electrical resistance and so will tend to heat up.
How do you determine the amount of stretch in a spring?
If you were to hold the bottom of the spring and pull downward, the spring would stretch. To determine this quantitative relationship between the amount of force and the amount of stretch, objects of known mass could be attached to the spring. For each object which is added, the amount of stretch could be measured.
