What happens when you compress and stretch a spring?
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 when you stretch a spring?
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 does a spring apply when it is stretched or compressed?
restoring force
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.
Does stretching a spring make it stronger?
In the case of an extension or torsion spring, there are less coils working together to provide that extension or torque so, again, you spring will be stronger, but it will be under more stress.
Why does a spring stop stretching?
When it stretches, we measure the extension – that’s how much longer it is than it was when we started. so long as we don’t exceed the elastic limit. The elastic limit is where the graph departs from a straight line. If we go past it, the spring won’t go back to its original length.
How do springs stretch?
A typical spring is a tightly wound coil or spiral of metal that stretches when you pull it (apply a force) and goes back to its original shape when you let it go again (remove the force). In other words, a spring is elastic. Some alloys have a property called shape-memory, which means they’re naturally springy.
When a spring is compressed the energy changes from kinetic?
When a spring is compressed, the energy changes from kinetic to potential.
When a spring is compressed does it have elastic potential energy?
Work is done when a spring is extended or compressed . Elastic potential energy is stored in the spring. Provided inelastic deformation has not happened, the work done is equal to the elastic potential energy stored.
When spring is compressed its potential energy increase or decrease?
When a spring is compressed or stretched, what happens to its potential energy? In either case, work has to be done. Therefore, potential energy of the spring increases.
Does stretching a spring weaken it?
Stretching the spring affects the length, and would allow more travel, but does not change the spring rate. Stretching the spring is usually a bad idea because full compression afterwards can yield the spring back to its original length.
Can you stretch or compress a spring?
You 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.
What happens to a spring when a force is applied?
On subsequent release of the stress, the spring will return to a permanently deformed shape. Whenever a force is applied on a spring, tied at one end, either to stretch it or to compress it, a reaction force comes into play which tries to oppose the change.
What happens to the elastic potential energy when a spring is compressed?
Every time the spring is compressed or stretched relative to its relaxed position, there is an increase in the elastic potential energy. The amount of elastic potential energy depends on the amount of stretch or compression of the spring.
How does mass affect the acceleration of a spring?
However, as the mass moves and the spring is less compressed, the force and acceleration decrease. Calculus integration would be necessary to deal with the diminishing acceleration. This problem is easier to deal with using energy formulas. The energy stored in a spring is Es = ½kx².
