Analyzing Different Types of Energy
In order for work to be done by machines or human beings, they need to
possess energy. It is measured in the same units as work, namely joule
(I) with practical values often being expressed in kilojoule (kJ),
megajoule or gigajoule (GJ). Energy, like work, does not possess
direction and is as quantity. It can take several forms and may be
converted from one form to another.
Kinetic energy
This is the energy that a body possesses because of its motion. The
greater speed at which it is moving the greater its kinetic energy.
The energy in if case is equal to the work done by the body in coming
to rest. A hammer possesses kinetic energy as it strikes a nail and
this energy enables it to do work driving the nail into a piece of
wood. Linear and angular motion both give rise to kinetic energy.
Potential energy
This is the energy that a body possesses because of its position in a
particular type of field: gravitational, electric, magnetic or
nuclear. Gravitational potential energy for example equals the amount
of work that the body can as it falls towards the Earth under the pull
of gravity. Potential energy, like kinetic, can be used to do useful
work. In a hydroelectric generating static for instance, water falls
from a higher level to a lower one and does work the turbines.
Strain energy
When a force is applied to a structure and causes it to distort, the
point of application of the force is changed and work is done. This
can be stored ii structure as strain energy or resilience (see section
8.11). If the force is removed this energy may be recovered and
converted to other ...

...ways. One system uses the relative movements of floating rafts
to convert the wave energy. Very large amounts of energy are
theoretically available, particularly in the winter when the
requirement is greatest.
Geothermal energy
We know that very high temperatures exist within the Earth and in some
places heat in practical quantities is available at the surface. Hot
springs have been used at least since Roman times. There are
installations in several countries, which use geothermal energy to
generate electricity.
Wind energy
Wind power has been harnessed for many centuries and is now seriously
considered for the generation of electricity. We can make a rough
estimate of the power available from a windmill by considering the
kinetic energy of the air approaching the circle swept out by the
blades.
To make them feel needed give them a new way to complete the same task that wouldn’t be able to be done by the new machines. (Texas)
Energy can never be created or destroyed. Energy may be transformed from one form to another, but the total energy of an isolated system is always constant.
I believe that the purpose of doing this is to allow me to demonstrate my understanding of Elastic potential energy. And the projectile concepts of the effect of changing potential into kinetic energy and for me to demonstrate my ability to apply elastic potential energy to a scientific investigation.

Robots are important to humans in the workforce, even though, it may not appear so. In Better than Humans: Why Robots Will- and Must- Take Our Jobs, Kelly initially unsettles the reader by noting that our, “job [will be] taken by machines”- if not already taken (Kelly 300). The reason why
Physical effort comprises getting up and moving around to complete your goal. Primarily, effort begins with being physical and always moving forward. What comes to mind when thinking about physical effort is my mother. Specifically, my mother is from Mexico, she lived a ghastly life there. She had already my older brother, and at the time she was pregnant with me. Identical to every mother in the world, she desired the best for us, but she just didn’t see a bright future for us in Mexico. Thus, my mother decided to go to the United States knowing that the journey would be dreadful. My mom was full of perseverance and used of lots of physical effort to give her kids a better life. Furthermore, my mother used all the physical effort she had with her while pregnant. As an illustration, my mother had to walk many miles on a desert-like terrain and even had to go barefoot for a while after going through a river with currents that felt like a hurricane, after that swim she just took off her shoes because they

“I shall briefly explain how I conceive this matter. Look round the world: Contemplate the whole and every part of it: You will find it to be nothing but one great machine, subdivided into an infinite number of lesser machines, which again admit of subdivisions, to a degree beyond what human senses and faculties can trace and explain. All these various machines, and even their most minute parts, are adjusted to each other with an accuracy, which ravishes into admiration all men, who have ever contemplated them. The curious adapting of means to ends, throughout all nature, resembles exactly, though it much exceeds, the productions of human contrivance; of human design, thought, wisdom, and intelligence. Since therefore the effects
Energy is an odd concept, it is something that is neither here nor there yet has a profound impact on everything, both organic and inorganic. However, energy surrounds us in more ways than is commonly believed; it is possible that matter is only a form of energy. In fact, according to Albert Einstein, matter and energy are different forms of the same thing (“Do Antimatter and Matter Destroy Each Other?”). Through analyzing the superposition of bosons (particles without mass) and fermions (particles with mass), transformations between energy and matter, the creation of mass, and the mass of energy, the existence of what humans consider to be matter will be questioned.
workability of the machine is just an objectification of this peace of mind. The ultimate

We would become like Vladimir and Estragon in Waiting for Godot-we would be doing nothing more than existing, which we have seen does not bring much happiness.
It is not ethical to replace human employees with robotic automation and computer-controlled systems. It is important to be mindful, how and when to use robotic automation as robotic automation is useful, when used sparsely. Robots are a problem for humans because, the technology of robots is becoming smarter, more reliable industrial robots and drones that lead to better factory production. It is often cheaper to buy an industrial robot or program than to train a human worker and pay them for their job. The major cost difference of robotic automation is often a major factor in why human jobs are replaced by robots, as with salary and overall price per employ.
Since the beginning of time, humans have thought and made many inventions. Repeatedly the newer one is better than the older. Our minds have created many remarkable things, however the best invention we ever created is the computer. computers are constantly growing and becoming better every day. Every day computers are capable of doing new things. Even though computers have helped us a lot in our daily lives, many jobs have been lost because of it, now the computer can do all of the things a man can do in seconds! Everything in the world relies on computers and if a universal threat happens in which all computers just malfunction then we are doomed. Computers need to be programmed to be able to work or else it would just be a useless chunk of metal. And we humans need tools to be able to live; we program the computer and it could do a lot of necessary functions that have to be done. It is like a mutual effect between us and he computer (s01821169 1).

To conclude, robots could be the backbone of the society that will result in a technological revolution. Because of robots various characteristics that do not experience fear, nor exhaustion and they are precisely programmed, which make them able to help in case of need, housework, and factories production. Society needs to put the issue of robots into consideration to satisfy any shortage exists in the world.
