Why is Earth considered to have zero potential[potential energy]...?
PE is relative. In one frame of reference, it can be zero and in another it can be something else.Rohit Mallya said:ok...
But is really P.E. zero...??
An object has 0 potential energy with respect to the point it is at.Rohit Mallya said:Anybody help..!
Not possible: there are an infinite number of possible reference frames. Frame choice is completely arbitrary.Rohit Mallya said:Please give examples for each frames...

No, it does not.Rohit Mallya said:But Sir potential energy means internal energy na?
Rohit Mallya said:But Sir potential energy means internal energy na?
Rohit Mallya said:ok so P.E. of Earth is takes to be 0 for convenience sake correct Sir?
Rohit Mallya said:yes Sir but if we forget and try to calculate Earth's potential what will be its value?
Rohit Mallya said:no I'm asking for earth.what will be Earth's actual value of potential energy?
Rohit Mallya said:It is very much relative na Sir?
The earth is considered to have zero potential energy because potential energy is defined as the energy an object has due to its position or configuration in a force field. Since the earth is constantly rotating and orbiting around the sun, its position and configuration are constantly changing, resulting in an overall average of zero potential energy.
While it is true that the earth has zero potential energy in the traditional sense, there are still forms of potential energy present on earth, such as gravitational potential energy and elastic potential energy. However, these forms of potential energy are constantly changing due to the earth's rotation and orbit, resulting in an overall average of zero potential energy.
The earth's rotation affects its potential energy by constantly changing its position and configuration in the Earth's gravitational field. This results in a constantly changing potential energy, with an overall average of zero.
The concept of potential energy is important for understanding the earth because it helps us understand the forces at work in the universe and how they affect objects. It also plays a crucial role in understanding phenomena such as gravity, orbits, and tides.
No, potential energy cannot be created or destroyed on earth. It can only be converted from one form to another. For example, potential energy can be converted into kinetic energy when an object falls, but the total amount of potential energy in the system remains the same.
