## What is force of spring?

The spring force is called a restoring force because the force exerted by the spring is always in the opposite direction to the displacement. Pulling down on a spring stretches the spring downward, which results in the spring exerting an upward force.

## What is an example of a spring force?

Simple examples are the movement of springs and pendulums, but there are many other situations in which oscillations occur. An important feature of periodic motion is that the object has a stable equilibrium position. Also, a restoring force which is directed toward that position.

## What is the equation for work done on a spring?

stretch for a spring. The blue line represents the graph of F = kx (Hooke’s Law). We know that the area shaded in red represents the work you would need to do to stretch the spring a distance x from its rest position. Since this area is a triangle, the shaded area = (1/2)(base)(height) = (1/2)(x)(kx) = (1/2)kx2.

F = kx

## Is spring force a constant force?

An ideal constant-force spring is a spring for which the force it exerts over its range of motion is a constant, that is, it does not obey Hooke’s law. In reality, “constant-force springs” do not provide a truly constant force and are constructed from materials which do obey Hooke’s law.

## What are 2 examples of forces?

Types of Forces

Contact Forces Action-at-a-Distance Forces
Frictional Force Gravitational Force
Tension Force Electrical Force
Normal Force Magnetic Force
Air Resistance Force

## How do you calculate spring pressure?

of pressure to compress the spring a full inch. If we have a camshaft providing a total valve lift of . 500 then we can calculate the pressure by multiplying the lift by the spring rate and adding that number to the installed pressure to determine the open pressure.

## What objects use springs?

Here are some typical places you will find springs:Ball point pen.Car shocks.Wire bound notebooks.Mattresses.Wind up toys.Pool diving board.Watches.Door locks.

## What is work formula?

Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d).

## Can work done by spring force be zero?

So for that time interval spring force is in opposite directions to displacement -the work done by spring force is negative. As soon as you leave the spring, the spring moves back towards 0 position that’s when the spring force is doing positive work. Force and displacement have same direction.

## What is the unit for spring constant?

newtons per meter

## What is spring constant k?

k is the spring constant, in Newtons per meter (N/m), and x is the displacement of the spring from its equilibrium position. The spring constant, k, is representative of how stiff the spring is. Stiffer (more difficult to stretch) springs have higher spring constants.

## Why is there a negative in F =- KX?

Though we have not explicitly established the direction of the force here, the negative sign is customarily added. This is to signify that the restoring force due to the spring is in the opposite direction to the force which caused the displacement.
