The laboratory is based on the assumption that at the two points of the motion being considered, the mass is at rest. What kind of energy does not need to be included under these experimental conditions

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

answer: 31, 5556. 952 seconds
