Potential energy is defined as the energy possessed by a body due to its position in the gravitational field.
Approximately it will be got by using the expression mgh.
m - the mass in kg
g-acceleration due to gravity
and h - the height above the surface of the earth
The other to find the potential energy so precisely is using the expression
G Mm/(R+h)2 or replacing GM by gR2 we get mg(R/R+h)2
Any way the details about h is not given. So finding the potential energy will be in complete.

What is the potential energy of a 20kg rock perched at the top of a hill with a height of 100 meters?
The potential energy of the rock can be calculated using the formula PE = mgh, where m is the mass of the rock (20kg), g is the acceleration due to gravity (9.81 m/s^2), and h is the height of the hill (100 meters). Substituting the values into the formula, we get PE = 20kg * 9.81 m/s^2 * 100 m = 19620 J. So, the potential energy of a 20kg rock perched at the top of a 100-meter hill is 19620 Joules.
Does a rock have potential energy?
Yes rocks do have potential energy. Potential energy is defined as energy stored within a physical system. It is called potential because it has the potential to be converted into other forms of energy, such as kinetic energy which can do work in the process. This means that a rock can have potential energy as simple as, a rock held at an elevation. If dropped it's potential energy is then being converted to kinetic energy.
The energy of position such as a rock on a hill is?
The energy of position for a rock on a hill is potential energy, specifically gravitational potential energy. This energy is stored in the rock due to its position above the ground and can be converted into kinetic energy if the rock rolls down the hill.
What type of energy is stored in a rock?
Potential energy is stored in a rock due to its position or composition. This energy can be released when the rock falls or breaks apart.
What energy has the failling rock?
The falling rock possesses potential energy as it falls due to gravity. This potential energy is converted into kinetic energy as the rock accelerates downward.

A force that adds potential energy to rock until the rock changes is?
The force that adds potential energy to a rock until the rock changes is gravity. As the rock is lifted against the force of gravity, potential energy is stored in the rock. Once the rock falls or is released, this potential energy is converted into kinetic energy, causing the rock to change position or state.
The energy of position such as a rock on a hill is?
The energy of position for a rock on a hill is potential energy, specifically gravitational potential energy. This energy is stored in the rock due to its position above the ground and can be converted into kinetic energy if the rock rolls down the hill.

Does a rock have potential energy on a hill?
Yes, a rock on a hill has gravitational potential energy due to its position above the ground. This potential energy can be converted into kinetic energy if the rock rolls down the hill.
A rock on top of a mountain has what energy?
Potential energy. Although if the rock is pushed, moved etc. it becomes kinetic energy
Do a rock sitting on top of a cliff has no energy?
If it's not moving it doesn't have any energy
What type of potential energy does a rock perched on the edge of a cliff have?
The rock perched on the edge of a cliff has gravitational potential energy due to its position above the ground. This potential energy is stored in the rock as a result of its vertical distance from the ground and can be converted into kinetic energy if the rock falls off the cliff.
Does a rock at the edge of a 200m high cliff has more potential energy than an equal sized rock at the edge of a 600m high cliff?
Yes, the rock at the edge of the 600m high cliff has more potential energy than the rock at the edge of the 200m high cliff. Potential energy is directly proportional to the height, so the higher the cliff, the more potential energy the rock has.
Why is a rock on the top of a hill kinetic energy?
A rock on top of a hill has potential energy, not kinetic energy. If it starts rolling down the hill then the potential energy transforms to kinetic energy.
