Where Does Mechanical Energy Come From?

Where does mechanical energy come from? Mechanical energy comes from all of the energy stored in a mechanical system.

Science has identified many forms of energy. The three main types of energy are:

• Mechanical energy
• Chemical energy
• Nuclear energy

Each of these different types of energy is generated from a different place.

Mechanial energy comes from energy stored in a mechanical system. A mechanical system is any group of things that interact with one another on the principles of basic mechanics. In a mechanical system, the only outside force that needs to be taken into consideration is the effect of gravity. The energy stored in a mechanical system is known as mechanical energy and this type of energy is made up of kinetic energy and potential energy.

What Is Kinetic Energy

So, we know where mechanical energy comes form- mehanical systems- but what exactly is the mechanical energy and what does it mean that it has both kinetic and potential energy?

Kinetic energy is defined as the total amount of energy that an object has while it is in motion. The motion of the object can be in any direction and there are several available directions that an object in motion can move. Kinetic energy simply describes the force behind an object to get that object to move. The farther and faster an object moves, the more kinetic energy it possesses.

Kinetic energy is can be described as the amount of force it would take to move the object from a state of perfect rest to the current speed at which it is moving.  Kinetic energy, however, does not describe the direction in which the object is moving. Kinetic energy is often described as the magnitude of an object. The equation used to calculate the amount of kinetic energy that an object possesses is:

Here the m equals the mass of the object and v equals the object’s velocity. Therefore, the kinetic energy of an object is equal to one half of its mass multiplied by its velocity squared.

This is the simple formula for calculating the kinetic energy of an object. There are circumstances that require more complex calculations in order to determine the kinetic energy of an object.

What Is Potential Energy

Potential energy is another type of energy produced by mechanical energy in mechanical systems and is also important to understanding where mechanical energy comes from and what it does.

Potential energy is defined as the stored energy in an object due to its position. The reason it is called potential energy is because it is not doing any work in its current state, yet it has the potential to be converted into different types of energy, like kinetic energy, if the correct amount of force is applied to put the object into motion. The normal unit used to measure this type of energy is known as a joule. The major principle behind potential energy is that energy can neither be created or destroyed in this form.

Example of Mechanical Energy

Mechanical energy exists in all mechanical systems. As an example, imagine a rubber band between two fingers. If you pull back on the rubber band, but do not release it, you have created a source of potential energy that has the ability to be converted into kinetic energy. If you let go of the rubber band, allowing it to move in a forward motion, you have created a source of kinetic energy.

As another example, imagine a wrecking ball. The ball is swung backwards away from a building. As the ball is swung backwards, potential energy is stored. When the ball is swung forwards to wreck the building, this is kinetic energy. This is where mechanical energy comes from and how it is used in everyday life.
