There are plenty of forms of power that exist in nature. But, castle all fall into two basic categories. These room kinetic and potential energy. And, as soon as you incorporate them, what you get is mechanical energy. In other words, by definition, mechanical energy is the amount of kinetic and also potential energy.

You are watching: What are two types of mechanical energy?

In this exclusive article, we will certainly talk around the different species of mechanically energy and their real-life examples. What is the power of motion? What is the energy of position? just how to calculate mechanically energy?

More importantly, what is the preservation of mechanically energy? Or, what room the resources of mechanical energy? no to mention, we will additionally talk around some the the to exclude, facts around mechanical energy. Therefore, i would indicate you stick through me it spins the end. Let’s dive right in!!!

Mechanical power Facts

Did you know that an item can have both potential power (due come its position) and kinetic power (due come its motion) only and only in the case of the macroscopic people i.e classical Physics, not in the microscopic people i.e Quantum Physics?

If an object can have both place (potential energy) and momentum (kinetic energy) in the quantum realm. It would straight violate the Heisenberg apprehension Principle.

Not come mention, there are some instances such together Quantum Entanglement whereby Heisenberg apprehension Principle does acquire violated. To know an ext about it, check out The EPR Paradox – A Thought, Myth, or, a Reality?


What is mechanically Energy?

By definition, mechanical energy is the sum of the kinetic and potential energy of a system. Not to mention, one can also define that the capability to do work or cause change as mechanical energy.

When ns say the power of motion, i am strictly referring to the kinetic energy of the system. Similarly, when I to speak the power of position, ns am strictly introduce to the potential power of the system.

On the other hand, once I speak the power of a mechanism or things due come its motion and also its position, i am strictly introduce to the mechanical energy of the system i.e nothing but the amount of kinetic and potential energy.

Conservation of mechanical Energy

According to the law of preservation of mechanical power definition, “energy have the right to neither be developed nor be destroyed, until or unless some sort of exterior forces prefer frictional forces or non-conservative pressures are applied”.

In other words, the total mechanical energy of a system is conserved. Therefore, energy can only transform from one type to another type of energy.

YEAH YEAH, you would certainly be reasoning that the above-mentioned an interpretation is the the law of preservation of energy i.e the first law of thermodynamics.

The writer of the post must be lying and also all. Well, let me clear the air. Neither i am lying, no one you space wrong. In fact, us both space correct. Confused????

Okay, stop take an instance to understand it properly. Not to mention, there can be so numerous examples to define the concept of the preservation of mechanically energy. The end of all, ns am going to define the most generic one. Keep reading!!!

Physics that Pendulum

We all space well conscious of the truth that what pendulum is and also what the does i.e swings earlier and forth!!! But, what us don’t know is that how it works? much more importantly, those the physics behind the working of a an easy pendulum.

Well, the physics that the pendulum is solely based on the conservation of mechanical energy. For starters, a pendulum is a mechanical system that works due to the consistent exchange in between kinetic and potential energy.

To make it much more simple, allow me bifurcate the physics the the pendulum into two cases. To placed it differently, permit me bifurcate the working of the pendulum right into two particular positions.

Case 1 – remainder or extreme Position

At an extreme position or in ~ rest, the bob of the pendulum is in ~ its preferably height. Therefore, as a result, it has actually the maximum potential energy and lowest kinetic energy.

WHY? since at this point, top top one hand, the bob has actually zero rate (zero kinetic energy). And, on the various other hand, that is farthest away indigenous the earth gravitational well (maximum potential energy). See the above diagram for appropriate understanding.

Case 2 – upright or median Position

Now allow the bob free to swing ago and forth. Therefore, as soon as the bob will the vertical or median position i.e its lowest height, it has the best kinetic energy and lowest potential energy.

WHY? since at this point, ~ above one hand, the bob has actually the maximum rate (maximum kinetic energy). And, top top the various other hand, it is nearest to the earth gravitational fine (zero potential energy). Check out the above diagram for suitable understanding.

Therefore, by moving ago and forth, the mechanical mechanism of the an easy pendulum has actually both kinetic and potential power which is constantly changing between the two. Therefore the mechanical power of the device is conserved i.e constant.

Not come mention, in the over example, we space neglecting the impacts of exterior forces favor drag forces and also frictional forces.

Mechanical power Facts

Did you understand that it to be English physicist James Prescott Joule who at very first experimentally demonstrated that because of friction a details amount of mechanical energy can be shed as thermal power (heat)?

In fact, he also successfully demonstrated that also if the mechanical power of a system (a straightforward pendulum) is shed as heat. Yet the overall or total energy the the system always remains constant.


Types of mechanical Energy

Till now, us have currently talked a lot around kinetic energy and potential energy. But, as a matter of fact, us don’t recognize what they are!! Or, like how they work? Therefore, without wasting any much more time, let me offer you a short review of both the them.

By definition, mechanical energy can it is in bifurcated into two parts. Or, one can say that there room two types of mechanical energy i.e kinetic and also potential energy.

Technically speaking, they room not the form or develops of mechanical energy. In fact, they are just the constituent of mechanical energy. Anyhow, let’s move ahead!!!

Kinetic energy – Mechanical power of Motion

According come the an interpretation of kinetic energy, when an object is in inert (motion), the has power in the form of kinetic energy. In various other words, the power of movement is referred to as kinetic energy.

Check out: What is Kinetic Energy? – Definition, varieties & Examples

Types the Kinetic Energy

Based on the kind of motion, we have the right to bifurcate kinetic power into three main sections. No to mention, over there are additionally some other methods to specify the types of kinetic energy. However, in this article, ns am only explaining it in comparison to the kind of motion.

Translational Kinetic power – due to straight-line activity of a bodyRotational Kinetic energy – as result of rotational motion of a bodyVibrational Kinetic energy – due to vibrational motion of a body


Potential energy – Mechanical power of position

The energy that is stored in an item due come its position is well-known as potential energy. In various other words, the power that is stored is referred to as potential energy. Well, ns would quite say no just because of that is position, there space some other factors too.

In general, one have the right to say the it’s the energy held by an object not only since of its place relative to various other objects. But also because of the stresses in ~ itself, its electric charge, or some various other factors.

In fact, based upon these factors that influence the potential energy of one object, it have the right to be more dissected into several parts.

Total Mechanical energy Formula

How to calculation the mechanical energy of a system? Well, that quite straightforward and straightforward. I typical just include the kinetic and also potential energy of a system. After that, what you obtain is the complete mechanical energy.

According to the an interpretation of mechanical energy, the amount of the kinetic and potential energy is the total mechanical energy of a system. Let’s view how!!!

Total mechanical power = Kinetic energy + Potential Energy



Kinetic power = ½mv²

Potential power = mgh

putting the worth of kinetic and also potential energy in the complete mechanical energy formula, we get:

TME = ½mv² + mgh


Mechanical power Facts

Did you recognize that the word mechanical energy only corresponds to the Newtonian mechanics i.e macroscopic world?

In the microscopic people i.e quantum mechanics, words mechanical power of a system is replaced with hamiltonian that a system.

In other words, in the quantum mechanical world, the hamiltonian of a device is same to the sum of the kinetic and also potential power of a system.

As you already know the by definition, mechanical power is nothing yet energy in conversion. In other words, over there are countless devices that are basically used to transform mechanical power into other creates of power or angry versa.

These types of gadgets are basically characterized as the various sources of mechanical energy. Some of them are provided below!!!

An internal combustion engine switch the chemical energy of fuel right into mechanical energy.An electrical motor converts electric energy into mechanical energy.The hydropower plant converts the mechanical (potential) energy of water into electrical energy.A vapor engine counter the heat energy of heavy steam into mechanically energy, etc.
