Question

The total mechanical energy of a system is conserved if the forces that act on it are ____.

Answer 1

Mechanical energy:

1. The total of kinetic and potential energy in a device or entity that is employed to perform a certain task is called mechanical energy.
2. In other words, it characterizes an object's energy as a result of its motion, location, or both.
3. The entire kinetic energy plus the total potential energy has been described as the platform's mechanical energy.

Conservation of mechanical energy:

The entire mechanical energy of a structure is conserved, which means that it cannot be generated or destroyed, it can only be internally transformed from one form to someone else if the forces acting on the system are sufficiently conservative in nature.

Mathematically, this can be represented as:

$\mathrm{C}=\mathrm{KE}+\mathrm{PE}$

Here,

C stands for some constant.

KE is the kinetic energy.

PE is the potential energy.

Therefore, the total mechanical energy of a system is conserved if the forces that act on it are conservative in nature.
