Whenever we compress or lengthen a stretched spring, we experience a force equivalent to the force we apply in the opposite direction. However, as soon as the stress is relieved, the spring returns to its original shape. The spring potential energy is what it’s called.
Potential Energy of a Spring
A spring can be found in practically every mechanical part of our lives, from automotive shock absorbers to kitchen gas lighting. Spring is used since of its ability to deform and then return to their original state. When a spring is stretched or compressed, it produces a force in the opposite direction. Whenever a spring differs from its mean position, it seeks to return to that point. Hooke’s law determines this force, which aids in the analysis of the energy stored in the spring.
Hooke’s law
An elastic object, including a metal spring or rope, requires force to stretch. If an elastic object is stretched or squeezed, it is said to be elastic. It tries to resist the change in shape by exerting power. Hooke’s law provides this force. The spring’s force is known as restoring force since it always acts in the opposite direction of the deformation.
According to Hooke’s law,
For short ranges, the force required to stretch an elastic object including a metal spring is precisely proportional to the spring’s extension. A negative sign is employed since the restorative force is in the opposite direction.
Where x is the displacement of the spring in relation to its unpadded length and F is the force it exerts. Then,
F=-Kx
The spring constant k, is used here.
Potential Energy
The energy possessed by an item as a result of its relative immovable location in space, tension, or electric charge is referred to as potential energy. Potential energy is one of the two basic forms of energy, whereas kinetic energy is the other.
Potential energy is the energy that an object retains as a consequence of its stationary location. Potential energy is the intrinsic energy of the body in its static position.
The two types of potential energy are elastic potential energy and gravitational potential energy.
Elastic Potential Energy
Elastic potential energy is the energy stored in materials which can be stretched or extended, including trampolines, rubber bands, and bungee cords. An object’s ability to expand is proportional to its elastic potential energy. Many objects, such as the twisted rubber band which propels a toy plane or the Coil spring in a wind-up clock, are designed to store elastic potential energy.
The elastic potential energy is calculated using the following formula:
U=1/2kx²
Here,
Where,
U is the elastic potential energy.
K is the constant of spring force.
X is the length of the string when stretched in metres.
Gravitational Potential Energy
As a consequence of a shift in its position, an object in a gravitational field obtains gravitational potential energy. Gravitational potential energy is an energy which is linked to gravity or gravitational force in simple words.
The gravitational potential energy is calculated using the following equation:
GPE=m×g×h
m refers to mass in kg.
The letter g stands for gravitational acceleration.
h denotes height.
Concept of Spring Potential Energy
Spring is a standard tool, and due to its small mass, their inertia is commonly disregarded. It’s a common occurrence whenever a spring is strained, it will deform owing to compression. As a consequence, when a spring compresses or extends a body, it exerts an equal and opposite force.
It’s the stored energy in a compressible or stretchable substance, such as a spring, rubber band, or molecule. It’s the force multiplied by the movement’s distance.
There is no energy in the spring when it is in its normal position, that is not strained. This is caused by the deformation of a certain elastic object, such as a spring. It also refers to the process of stretching the spring.
Spring Potential Energy Formula
Whenever an object repeats its motion in a predetermined cycle, it is said to be in periodic motion. Oscillation is another term for this type of motion. Spring and pendulum movement are simple instances, but there are numerous additional situations in which oscillations occur. One of the most significant characteristics of periodic motion is that the item maintains a stable equilibrium position.
A restoring force also works for string, which means that string has potential energy.
Potential Energy of a Spring Formula
String potential energy=force×distance or displacement
In consequence, the force is equal to the displacement of the spring constant.
A spring’s potential energy is:
P.E=1 ⁄ 2k×x²
Gravitational potential energy spring work
Since the spring is stretched to its full extension, its potential energy is at its highest. Because the mass is elevated the least amount above earth, the potential energy owing to gravity is at a minimum.
Spring-mass potential energy equation
String potential energy=force×distance or displacement
Conclusion
A spring can be found in practically every mechanical part of our lives, from automotive shock absorbers to kitchen gas lighting. Spring is used since of its ability to deform and then return to their original state.
