Heartwarming Mechanical Energy Formula

This means that potential energy can become kinetic energy or vice versa but energy cannot disappear.

Mechanical energy formula. Mechanical energy is due to the position or movement of an object. Energy is a scalar quantity and the mechanical energy of a system is the sum of the potential energy which is measured by the position of the parts of the system and the kinetic energy which is also called the energy of motion. Work involves a force through which an object can be displaced.

When the work is done upon the object then it will gain energy. Mechanical Energy formula is derived from KE and PE formula where Kinetic energy is 12 multiplied by mass and velocity square and potential energy is mass multiplied by gravity and height. This video explains the standard equation for Conservation of Mechanical Energy used in general physics.

As already mentioned the mechanical energy of an object can be the result of its motion ie kinetic energy andor the result of its stored energy of position ie potential energyThe total amount of mechanical energy is merely the sum of the potential energy and the kinetic energy. The precise formula for kinetic energy in terms of speed and mass is not easy to guesshowever. An objects ability to do work is measured by its mechanical energy or the sum the objects kinetic energy and potential energy.

Law of Conservation of Mechanical Energy. Friction air resistance remains constant. The mechanical energy of the system is defined as the total kinetic energy plus the total potential energy.
