Neet | Class 11 | Principle of Total Mechanical Energy |Upadhyay Sir

Total mechanical energy is the sum of kinetic energy (the energy of motion) and potential energy (stored energy due to position or configuration) of an object or a system. It is a fundamental concept in physics and engineering, and is typically denoted by the symbol "E" or "ET".

The total mechanical energy of an object or system is the sum of its:

1. Kinetic energy (KE): the energy of motion, dependent on the object's mass and velocity.
2. Potential energy (PE): stored energy due to the object's position, shape, or configuration, such as gravitational potential energy, elastic potential energy, or electrical potential energy.

The formula for total mechanical energy is:

ET = KE + PE

For example, a rolling ball has kinetic energy due to its motion, and potential energy due to its height above the ground. As the ball rolls down a hill, its potential energy converts to kinetic energy, but the total mechanical energy remains constant (assuming no energy losses due to friction or other factors).

Conservation of total mechanical energy is a fundamental principle in physics, meaning that the total mechanical energy of a closed system remains constant over time, but can be converted from one form to another.
