A object has one joule of potential energy explain what does it means?

∙ 13y ago
We know that energy is defined as the ability to do work.So an object has one joule of potential energy means that the body has capability to do a work of one joule.
We may say that the object with 1 joule of potential energy is the force field and our work is stored in displacing the object against the field

∙ 13y agowell potential energy of an object means the amount of work that will be required to bring that object from infinity to that point...
work done = (potential energy final) - (potential energy initial)
now we assume potential energy at infinity to be 0 joule
hence potential energy at final position = work done
therefore one joule of potential energy will mean that we will need to do one joule of work to bring that object from infinity to that point

∙ 14y agoPotential energy is energy that is not obviously present. Energies such as heat, light and sound are all present energies, but a stretched out spring, or a chemical with the potential to react has potential energy.

It's mean it has ability to do work of 1 joule

Is running an kinetic or potential energy?
The potential energy of the mass of the sky diver is transformed into kinetic energy during the free fall. The kinetic energy of the free fall is transformed into kinetic energy and heat of the air when the parachute is deployed.
Why does kinetic energy depend on mass and speed?
Since kintetic energy is the energy of motion it depends on the two. mass affects inertia and inertia applies to kinetic energy. and speed is applied because the faster it going the more kinetic energy the object has.
What is cell potential in an electrochemical cell?
A galvanic cell is set up by generating a redox reaction, whose current is used to do work and the chemical energy is changed to electrical energy. Remember that a full oxidation-reduction reaction can be broken down to two half-reactions, one oxidation (loss of electrons) and one reduction (gain of electrons). There is a transfer of electrons from the anode (oxidation) to the cathode (reduction). There is a driving force that pulls the electrons from the anode to the cathode. This force is the cell potential of the electrochemical cell. It is measured in volts, which is 1 joule of work per Coulomb of charge transferred. Cell potential can be measured through a voltmeter. A voltmeter draws current through a known resistance. Notice, that a voltmeter is not precise because frictional heating occurs in the wire and uses some of the energy of the cell, so the number we get is actually less than the actual cell potential. It would be ideal to find the cell potential under zero current using a potentiometer. In these conditions, the cell potential has the same magnitude but opposite sign to the voltage of the potentiometer.
Explain what happens to the mass that is lost when a nucleus forms?
The mass isn't really lost, it's converted to energy via E=mc². The same thing happens in chemical reactions, it's just not noticeable. For example, burning one mole of carbon produces about 393500 J. Using E=mc² 393500 J=m(3.00x10^8 m/s)² m=393500 J/(3.00x10^8 m/s)² =4.37x10^-12 Kg Note that a Joule(J) is a (Kg∙m²)/s² so that's why the units cancel out to give Kg. Anyways, you see that the mass "lost" is very small, if you don't understand how small 4.37x10^-12 Kg is, write it out, it's 0.00000000000437 Kg. A good analytical balance wouldn't even be able to detect such a small "loss" in mass. However when we're dealing with nuclear reactions we're usually talking about converting mass to energy and because E=mc² and the speed of light(c) is such a large number we get a lot of energy from a small "loss" in mass! That's the only reason we care about the small "loss" in mass when we're talking about nuclear reactions. Notice that I put the word "loss" in quotations because like I said, the mass is not really lost, it's just converted to energy.
How water is a good regulator of body temperature?
Water has an amazingly high specific heat compared to most substances so for example: adding or removing 1 Joule of energy from 1000 cm3 of water will change its temperature much less than it would change 1000 cm3 of most other substances.
What does the joule explain about energy?
The joule doesn't "explain" anything; it is simply a unit used to measure energy.
What is the SI unit for potential energy?
It is a Joule.
What are the metric units for potential energy?
The unit for energy is the joule.
If you had 70 joule of potential energy and converted it into 55 joule of kinetic energy what happens for the missing 15 joule?
it dies and fades away
What is the SI unit for Gravatational Potential Energy?
Joule
What is an example of a joule?
A joule is simply a unit to measure energy. Examples of energy include gravitational potential energy, kinetic energy, sound energy, light energy, elastic energy, nuclear energy.
What is the unit for potential and kenetic energy?
The international unit for any type of energy is the joule.
What is the potential energy of a 100kg object when it is raised to a height of 5.00m?
PE=mgh (mass x gravity x height). Use 9.8 for gravity. Answer is in joule.
What is the si unit for potential energy difference?
Potential energy is measure in Joules (J). A Joule is a Newton*meter (N*m)
What is the definition for potential energy?
The stored energy that an object has due to its position or chemical composition. Potential energy can be thought of as energy stored within a physical system. It is called potential energy because it has the potential to be converted into other forms of energy, such as kinetic energy, and to do work in the process. The standard (SI) unit of measure for potential energy is the joule, the same as for work, or energy in general. The term "potential energy" was coined by the 19th century Scottish engineer and physicist William Rankine.[1]
