What is mechanical energy?
138502
Mechanical energy is one of several forms of energy. It is distinguished by the property that it can be transferred from one system to another by forces known to Newtonian mechanics, and includes kinetic energy and potential energy. The conservation of mechanical energy is a principle which states that, under certain conditions, the total mechanical energy of a system is constant.

No because of Kinetic energy.\n\nLesson 1: Basic Terminology and Concepts\nKinetic Energy\nKinetic energy is the energy of motion. An object which has motion - whether it be vertical or horizontal motion - has kinetic energy. There are many forms of kinetic energy - vibrational (the energy due to vibrational motion), rotational (the energy due to rotational motion), and translational (the energy due to motion from one location to another). To keep matters simple, we will focus upon translational kinetic energy. The amount of translational kinetic energy (from here on, the phrase kinetic energy will refer to translational kinetic energy) which an object has depends upon two variables: the mass (m) of the object and the speed (v) of the object. The following equation is used to represent the kinetic energy (KE) of an object.

Energy comes in many forms, right? Electrical, kinetic, potential, heat, chemical etc. And energy can be converted between these forms right? i.e. when you drop something from a height, potential energy is converted into kinetic energy. Same thing when you release a compressed spring. \n\nThe quality of energy refers to the ease with which you can harness it for use and conversion to other forms. For example the energy stored in a battery is high quality energy, since it's easy to harness for use. The ambient heat energy in a room, on the otherhand, is low quality energy, since it not easy or practical to extract the energy for use.

Energy can not be created or destroyed, it just changes into a different form.  Usually sound waves mechanically vibrate objects, sometimes transferring the energy into kinetic energy, sometimes it is reflected or absorbed and ultimately results in heat, which is a form of mechanical vibration.

hey men first know wat is a turbine.\nA turbine is a prime-mover used to provide the mechanical energy required for the generator.\nPrinciple of generators:\nwhenever a flux linking in a conductor changes there is an emf induced in the conductor.\n\nhere the flux is provided initially by a battery or some electrical source and the mechanical energy is provided by the turbine.\n\nIf u see the Mechnical energy from the turbine is converted into electrical.\nRemember energy can be converted from one form to another.This is the basic law.

I think what you are really asking is what different forms of energy convert to other forms of energy.  Mechanical energy can be converted to heat through friction.  Electrical energy can be converted to sound energy with the use of varying electrical currents and permanent magnets.  The splitting of atoms releases huge amounts of electromagnetic radiation of a huge variety, from electrons, to photons, heat, light, etc.  Light energy (photons) can interact with semiconductors in solar cells to produce electrical energy, also known as electromotive force.  I am sure someone has a comprehensive list of the primary energies that we know about.  \n\nIt may help, however, to discuss energy in terms of storing it.  Gas under high pressure in a closed cylinder has high potential energy.  The release of this pressure can cause thrust (like a rocket), or cause a super-sonic shock wave that can blow things up.  Certain chemicals have energy stored in them which is released through chemical reactions.  A rotating wheel has energy stored in the mass about the rotating axis, known as rotational momentum.  The magnetic field in an inductor, like a vehicle ignition coil stores energy in the field in the core, and releases it when the current to the coil is interrupted.  \n\nIn simpler terms, mechanical energy can be turned into heat, light, electromotive force, or pressure. Chemical energy can make heat, light, electromotive force, or pressure (not a complete list).  Atomic reactions (fission or fusion) release huge amounts of energy all across the electromagnetic spectrum.  Hope this is food for thought...\n\nSee a study of thermodynamics and entropy.  It would appear that all energy flow is headed in only one direction, always at a net loss.  See the link.

Kinetic energy (SI unit: the joule) is energy that a body possesses as a result of its motion. It is formally defined as the work needed to accelerate a body from rest to its current velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. Negative work of the same magnitude would be required to return the body to a state of rest from that velocity.

Although the words are used in many ways, science has specific definitions\nfor each.\n\nForce is a push or a pull.  Force is between objects, one object pushing or\npulling on another.\n\nEnergy is more difficult to define, because energy is "abstract".  Energy is\na quantity that gives an object the ability to affect other objects.  There\nare different kinds of energy.  Kinetic energy is the energy of motion,\nstored within a moving object.  Potential energy is stored in the force\nbetween objects, perhaps in the stretch of a spring.  Thermal energy can be\nstored in the temperature of an object.  Energy passes from place to place,\nobject to object, but never disappears.  The total energy of the universe\nremains constant.\n\nFuel is a material that has energy stored in its chemical structure.  When\nfuel is processes (burned, for example), the chemical energy is released.\nThis released energy can become heat and cause the temperature of something\nto rise.  The released energy can become the kinetic energy of a car.  It\ncan become the energy carried by sound to your ears.

DEFINITION:\n\nKinetic energy of a moving body is defined as the work done to bring it to rest. \n\n\nILLUSTRATION: \n\nIf a particle of mass 'm' is moving with velocity 'u' along a straight line and if a force 'F' is applied (in a direction opposite to its velocity) on it to bring it to rest after travelling 's' distance then the work done to bring the body to rest from its present state of motion is '-F*s' (force*displacement; - sign appears as work is done on the body and not by the body). \n\nWe know from mechanics 'V^2=u^2+2*f*s'_______(1) \nwhere 'v'=final velocity, 'u'=initial velocity and 'f'=constant acceleration of a particle in rectilinear motion (i.e. motion in a straight line).\n\nHere final velocity is zero as the body comes to rest finally, so v=0.\n\nAlso, f=F/m (since from Newton's second law F=m*f).\n\nSubstituting these values of 'v' and 'f' in eqn. (1) we get\n0 = u^2+2*(F/m)*s\nor s=-(m*u^2)/(2*F)___________(2)\n\nThus the work done to bring the body to rest from its present state of motion = -F*s = (-F)*{-(m*u^2)/(2*F)} = (m*u^2)/2. This is the expression for kinetic energy of a body in translation.\n\nUNIT:\n\nS.I. unit: Joule\nM.K.S. unit: erg\nN.B.: 1Joule=10^7erg

A mechanical wave exists in a medium (which on deformation is capable of producing elastic restoring forces) through which they travel and can transfer energy from one place to another without any of the particles of the medium being displaced permanently; there is no associated mass transport.

Technically a device that converts mechanical energy into electrical energy is usually called a transducer unless it is generating power at which point it is usually called a generator.\n\nSo a generator is a spinning magnet in a coil of wire. Spinning the magnet generates electricity in the coil. Examples of transducers include phonograph needles, sonar crystals, and BBQ grill lighters. These use a piezoelectric device to convert mechanical energy to electricity.

Kinetic energy is energy due to motion and potential energy is energy due to position in a force field.  The formula for translational kinetic energy is KE = 0.5*m*v^2, where m is mass and v is velocity.  The most common type of potential energy is gravitational potential energy, and near the surface of the Earth (or some other planetary body) the formula is PE = mgh, where m is mass, g is acceleration due to gravity, and h is the height above the surface.  Another common one is elastic potential energy in a compressed spring.  In that case the formula is PE = 0.5*k*x^2, where k is the spring constant and x is the compression.  An object can also have electrical potential energy, if it has an electrical charge and is positioned some distance from another charge.

Energy can be classified as either stored (potential) energy and working (kinetic) energy.\nPotential Energy = the energy that an object has as the result of its position or state.\nKinetic Energy = the energy that appears in the form of an object’s motion. KE = 1/2mv2

Kinetic Energy describes the amount of energy an object has by virtue of it hasving some non-zero mass and traveling at some speed.\nKE= 1/2 mv^2\n\nPotential Energy describes the energy that could be gained by that object if it was not at that potential.  It is not really accurate to say that potential energy is energy at rest since it is very possible for moving objects to have potential energy.\nA good example would be a rock sitting on a cliff.  That rock has some potential gravitiational energy since it is sitting some height above the ground (the bottom of the cliff).  The potential energy equals the amount of energy needed to put that rock up there in the first place and the amount of energy which could be gained if the rock falls down from the cliff.  As the rock is falling, before it hits the ground, the rock has some fraction of its potential energy converted into kinetic, in other words it has both at the same time.\nThere are many forms of potential energy, gravitational potential energy being the most commonly described.\ngravitational PE = mgh
