Work done by friction? increases kinetic energy of body
decreases kinetic energy of body
increases potential energy of body
decreases potential energy of body

yes it increases kinetic energy of body on which it is applying it also cause heat loss

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

technology is the application of the knowledge gained by science.
