Potential vs. Kinetic Mechanical Energy There are two types of mechanical energy: potential energy stored energy of position and kinetic energy energy of motion. Potential Mechanical Energy When an object is able to move but does not have a force working upon it, it is storing potential mechanical energy. The two main types of potential energy are: Gravitational Potential Energy: Energy that is stored in the height or position of an object.
Heavier objects possess higher amounts of gravitational energy. Kinetic Mechanical Energy An object uses kinetic mechanical energy when it is currently moving. In addition to mechanical energy, the four types of kinetic energy include: Radiant Energy : Energy produced by light waves Electrical Energy : Energy produced by electricity Sound Energy : Energy produced by sound waves Thermal Energy : Energy produced by heat No form of energy can be created or destroyed.
Mechanical Energy Conversions Any transferred energy that causes an object to do work is an example of energy conversion. Becoming Mechanical Energy Here are some examples of ways that different types of energy become mechanical energy.
Gasoline converts chemical energy to mechanical energy in cars. Steam engines convert thermal energy into mechanical energy in a train. Your body converts chemical energy from nutrients to mechanical energy for movement. A power drill converts electrical energy to mechanical energy when plugged in and used.
Music converts sound energy to mechanical energy in your eardrum. Converting Mechanical Energy Conversely, mechanical energy can convert into different types of energy. Windmills convert mechanical energy to electrical energy in homes. Hitting a drum converts mechanical energy to sound energy.
Any object that possesses mechanical energy - whether it is in the form of potential energy or kinetic energy - is able to do work. That is, its mechanical energy enables that object to apply a force to another object in order to cause it to be displaced. Numerous examples can be given of how an object with mechanical energy can harness that energy in order to apply a force to cause another object to be displaced. A classic example involves the massive wrecking ball of a demolition machine.
The wrecking ball is a massive object that is swung backwards to a high position and allowed to swing forward into building structure or other object in order to demolish it. Upon hitting the structure, the wrecking ball applies a force to it in order to cause the wall of the structure to be displaced.
The diagram below depicts the process by which the mechanical energy of a wrecking ball can be used to do work. A hammer is a tool that utilizes mechanical energy to do work.
The mechanical energy of a hammer gives the hammer its ability to apply a force to a nail in order to cause it to be displaced. Because the hammer has mechanical energy in the form of kinetic energy , it is able to do work on the nail. Mechanical energy is the ability to do work. Another example that illustrates how mechanical energy is the ability of an object to do work can be seen any evening at your local bowling alley.
The mechanical energy of a bowling ball gives the ball the ability to apply a force to a bowling pin in order to cause it to be displaced. Because the massive ball has mechanical energy in the form of kinetic energy , it is able to do work on the pin.
A dart gun is still another example of how mechanical energy of an object can do work on another object. When a dart gun is loaded and the springs are compressed, it possesses mechanical energy. The mechanical energy of the compressed springs gives the springs the ability to apply a force to the dart in order to cause it to be displaced. Because of the springs have mechanical energy in the form of elastic potential energy , it is able to do work on the dart. A common scene in some parts of the countryside is a "wind farm.
The mechanical energy of the moving air gives the air particles the ability to apply a force and cause a displacement of the blades. As the blades spin, their energy is subsequently converted into electrical energy a non-mechanical form of energy and supplied to homes and industries in order to run electrical appliances.
Because the moving wind has mechanical energy in the form of kinetic energy , it is able to do work on the blades. Once more, mechanical energy is the ability to do work. As already mentioned, the mechanical energy of an object can be the result of its motion i. The total amount of mechanical energy is merely the sum of the potential energy and the kinetic energy.
This sum is simply referred to as the total mechanical energy abbreviated TME.
