Calculate the rotational energy of a segment, given mass of the segment is 2.2 kg, moment of inertia is 0.57 kg-m2, and angular velocity is 25 rad/s.

To solve this problem we will use the concepts given by the rotational kinetic energy which describes the energy in a body product of its moment of inertia and its angular velocity, mathematically this is given as,

Where,

I = Moment of Inertia

= Angular Velocity

Replacing with our values we have that,

Therefore the rotational energy is 178.125J

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
