Normal force, weight, Kinetic friction, and air resistance are a few I think of the top of my head.

Louder than a sound with less energy
Answer:
In summary kinetic energy is not necessary
Explanation:
In this problem we are asked to indicate what type of energy does not need to be considered.
As they indicate that the masses do not move, scientific energy is defined by
K = ½ m v²
Since the velocities of the mass are zero, this energy is zero, so it is not necessary to take them into account in our analyzes.
In summary kinetic energy is not necessary
