This document discusses mechanical energy and its conservation. It introduces James Joule, a 19th century English physicist known for his research connecting electricity, thermodynamics, and the concept of energy. Mechanical energy is conserved in closed systems where purely mechanical forces act, but can be transformed between different forms, such as potential, kinetic, or other types like hydroelectric, wind, and tidal energy. Kinetic energy specifically refers to the energy an object possesses due to its motion, and is defined based on the work required to accelerate a mass from rest to its current speed.

Good morning, our topic is mechanical
energy and we´regoing to talk about
mechanical energy.
Mechanical energy
James PrescottJoule (Salford, December
24, 1818; October 11, 1889) wasan
English physicist, oneof the most
notable physicists of his time, known for
his research in electricity,
thermodynamics and energy. He studied
magnetism, and discovered its
relationship to mechanical work, which
led him to the theory of energy. The
international unit of energy, heat and
work, July was named in his honor. He
worked with Lord Kelvin to develop the
absolute scale of temperature, made
observations on the thermodynamic
theory (Joule-Thomson effect) and found
a relationship between electric current
through a resistanceand the heat
dissipated, now called Joule's law
moving body.

The mechanical energy is conserved,
therefore, is not created nor destroyed.
In the case of open systems formed by
particles interacting through purely
mechanical forces or conservative
fields, energy will remain constant over
time. Anyway, thereare cases of
particle systems in which mechanical
energy is not conserved.
Among the types of mechanical energy
are the following: Hydropower (. Will
drop water and the potential energy
you get fromit will use its recurrentuse
is to produceelectricity and to move
flour mills), wind energy (the produce
winds generated in the Earth's
atmosphere. it is also used at the
behest of electricity production as a
means of extracting groundwater or
certain types of mills for agriculture)
and tidal energy (produced by the
movement of the tides and the waves,
also can be transformed into electrical
energy).
In physics, thekinetic energy of a body
is the energy that possesses dueto its
motion. Itis defined as the need to
accelerate a body of a given mass from
rest to the speed indicated work.
Having gained this energy during
acceleration, the body maintains its
kinetic energy unless its speed changes.
