Formulate the principle of conservation of mechanical energy, with or without the presence of non-conservative forces; Use the conservation of mechanical energy to calculate various properties of simple systems
The law of conservation of energy states that the total energy is constant in any process. Energy may change in form or be transferred from one system to another, but the total remains the same. When all forms of energy are considered, conservation of energy is written in equation form as.

The principle of conservation of energy states that: Energy cannot be created or destroyed, it can only be transferred from one store to another. The principle of conservation of energy means that for a closed system, the total amount of energy is constant.
The Work/Energy Principle: The change in the energy of an object is equal to the net work done on the object. Modeling Tools for use with Energy including examples.
Formulate the principle of conservation of mechanical energy, with or without the presence of non-conservative forces; Use the conservation of mechanical energy to calculate various properties of simple systems
If you know the potential energies for the forces that enter into the problem, then forces are all conservative, and you can apply conservation of mechanical energy simply in terms of potential and kinetic energy. The equation expressing conservation of energy is: \(\mathrm{KE_i+PE_i=KE_f+PE_f.}\) .
We found the speed directly from the conservation of mechanical energy, without having to solve the differential equation for the motion of a pendulum (see Oscillations). We can approach this problem in terms of bar graphs of total energy.
