consider two bodies A and B of equal masses.Suppose thatthe body A is on the ground and the body Bis ata height h above the ground.What can you say about the difference in the gravitational potential energies of the two bodies? please explain

Since this is not my area of expertise, I searched Google under the key words "'gravitational potential energies' mass altitude" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps. Thanks for asking.

To understand the difference in the gravitational potential energies of bodies A and B, we need to consider the formula for gravitational potential energy and how it is affected by the height difference.

Gravitational potential energy (PE) is given by the equation:

PE = m * g * h

Where:
- PE is the gravitational potential energy
- m is the mass of the object
- g is the acceleration due to gravity (approximately 9.8 m/s^2 on Earth)
- h is the height of the object above a reference point (in this case, the ground)

In this scenario, both bodies A and B have equal masses. However, body A is on the ground (h = 0), while body B is at a height h above the ground.

For body A:
PE(A) = m * g * 0 = 0

Since the height (h) is zero, the gravitational potential energy of body A is zero.

For body B:
PE(B) = m * g * h

Since body B is at a height h above the ground, the gravitational potential energy is nonzero. Its value is determined by multiplying the mass, the acceleration due to gravity, and the height.

Therefore, the difference in gravitational potential energies between bodies A and B is given by:

PE(B) - PE(A) = m * g * h - 0 = m * g * h

The difference in the gravitational potential energies depends solely on the height (h) above the ground and the mass (m) of the objects. In this case, the difference is m * g * h.
