Mechanical Energy Facts

Mechanical Energy Facts
The mechanical energy of an object is the sum of its energy in motion and its stored motion. This means it is the sum of its kinetic and potential energy. Although the kinetic and potential energy of an object can change, its mechanical energy remains constant. This is because kinetic and potential energy change proportionately.
Interesting Mechanical Energy Facts:
Every object in motion contains mechanical energy.
The Law of Conservation of Mechanical Energy says that an objects mechanical energy remains constant under normal circumstances.
Although mechanical energy cannot be created nor destroyed, it can be converted to another type of energy.
Although other forces are always working on an object, they are normally so small that they do not change the amount of mechanical energy the object has.
Machines such as steam engines can convert mechanical energy into other forms of energy.
The mechanical energy of an object is associated with the objects' position and motion.
In a few cases, some mechanical energy is converted to heat resulting in less mechanical energy.
Some machines or devices can convert heat into mechanical energy.
The electric motor makes mechanical energy from electrical energy while a generator performs the opposite.
The job of a hydroelectric power plant is to make electrical energy from the mechanical energy of water that is stored in dams.
A turbine, such as a wind turbine, converts the kinetic energy of gas or steam into mechanical energy.
When an object loses mechanical energy, it gains heat or increases in temperature.
James Joule is the physicist who discovered the relationship between the loss of mechanical energy and the gain of heat.
If an object contains mechanical energy, then it has the ability to do work.
A wreaking ball, sound, and a bird all contain mechanical energy.
