If a spring constant of 128N/m is compressed by 0.18 m , how much potential energy is the spring?

2.1J

Explanation:

Given parameters:

Spring constant  = 128N/m

Compression  = 0.18m

Unknown:

Potential energy of the spring  = ?

Solution

The potential energy of the spring is the elastic potential energy within the spring.

 To solve this;

   Elastic potential energy  =  k e²  

k is the spring constant

e is the compression

 Now;

     Elastic potential energy  =   x 128 x 0.18²  = 2.1J

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
