Is work negative when spring is compressed?

Is the work done by spring force is always negative The answer is again no,when you stretch/compress a spring the work done by spring force is negetive but when you release the stretched/compressed spring work done by spring force is positive.

What happens to the work done when a spring is stretched or compressed?

A spring does negative work when you stretch it or compress it. Spring force is always towards the point of natural length (PNL) and hence, when you expand or compress it, the force is towards the PNL and the displacement is away from the PNL, so work done by spring force is negative in both instances.

Can the work of a spring be negative?

The minus sign indicates that the spring force is always opposite in direction to the displacement of its free end. So the work done by a spring force is always negative.

When a spring is compressed or stretched?

Hooke’s Law If an outside force (Fapplied) does work on the spring to stretch or compress it then the spring will gain energy. This type of energy the spring gains is called elastic potential energy.

Why is the spring constant negative?

k, being the spring constant, is always a positive number. the negative sign indicates that the restorative force is in the opposite direction of the applied force.

What is the work done in a spring?

Spring potential energy Distance here is the displacement in the position of the spring. From the equation, it is clear that the work done by the force of spring depends only on the endpoints of displacement. Also, we can see that in a cyclic process, the work done by the springs force is zero.

What happens when a spring is stretched too far?

When an elastic object is stretched beyond its limit of proportionality, the object does not return to its original length when the force is removed. In this instance, the relationship between force and extension changes from being linear, or directly proportional, to being non-linear.

Why is the spring force negative?

The spring force is called a restoring force because the force exerted by the spring is always in the opposite direction to the displacement. This is why there is a negative sign in the Hooke’s law equation.

When a spring is compressed the work is done on the spring therefore the elastic potential energy?

This work done is stored in spring as elastic potential energy (PE) when the spring is compressed and hence elastic potential energy decreases.
