## What is meant by gravitational potential?

Description. The gravitational potential at a point in a gravitational field is the work done per unit mass that would have to be done by some externally applied force to bring a massive object to that point from some defined position of zero potential, usually infinity .

## What is meant by gravitational potential energy derive expression for it?

Gravitational potential energy is the potential energy possessed by a body due to its position relative to the centre of earth. For a body placed at a height above the ground, the gravitational potential energy is measured by the amount of work done in lifting it up to that height against the force of gravity.

W=mgh.

## Is gravity infinite energy?

No, gravity can not be used as an infinite energy source. The kinetic energy that water gains when it falls (and can therefore be converted into electricity by a hydroelectric plant) comes ultimately from sunlight and not from gravity. As a force, no energy can be extracted from gravity itself.

## What is difference between gravitational potential and gravitational potential energy?

1 Answer. -Gravitational potential is the work done for a unit mass when it is brought from infinity to a certain point. -Whereas, GPE is energy an object possesses because of its position in a gravitational field. GPE is the work done when you move a body from infinity to the point.

## How do you solve for gravitational potential energy?

Show that the gravitational potential energy of an object of mass m at height h on Earth is given by PEg = mgh.

## What is maximum value of gravitational potential and where?

The gravitational potential increases as we move towards infinity and its maximum value is zero at infinity. can be used to describe the potential energy in a system of point charges (or radially symmetric spheres) as a function of their separation distance r, then the maximum value is zero, at infinite separation.

## What is the best example of potential energy?

What are some examples of potential energy? A rock sitting on the edge of a cliff. If the rock falls, the potential energy will be converted to kinetic energy, as the rock will be moving. A stretched elastic string in a longbow.
