Formula for Gravitational potential is - G M / r
Here G is universal Gravitation constant, M - mass of the planet and r is the distance of the point from the centre of the planet. The unit is J/kg
If potential energy is needed then the potential is to be multiplied by the mass m. So gravitational potential energy = - G M m / r
So the unit would be J (joule)

How high up is a 3 kg objectthat has 300 joules of energy?
Use the formula for gravitational potential energy (PE=mgh), and solve for height.
How do you solve What is the potential energy of a rock that weighs 100 newtons that is sitting on top of a hill 300 meters high?
Just use the formula for gravitational potential energy:GPE = mgh Earth's gravity is around 9.8 newton/kilogram (it varies a bit, depending where you are located). The answer will be in joules.
A bike rider approaches a hill with a speed of 8.5 ms the total mass of the bike and the rider is 85 kgit has a kinetic energy of 3.1x103 Joules No frictionWhat height will the bike if come stop?
You can use the formula for kinetic energy to verify the total kinetic energy (KE = 0.5mv2). Then, assuming all the energy is converted to (gravitational) potential energy, use the formula for potential energy, and solve for height. (PE = mgh)
What is the mass of a diver whose gravitational potential energy changes by 4441 Joules when diving into water from a height of 3.6 meters?
This is actually a relatively simple question. Gravitational Potential Energy is defined as Mass times Height times the gravitational constant. mgh is the formula. We set this equal to zero. mgh = 4441J. We know the height, 3.6 meters and the gravitational constant, which on earth is 9.8 meters per second squared. We then solve for m. m = 125.88kg. Hope this helps!
What is the formula to solve Gravitational Potential Energy?
E (joules) = mgh where: m = mass (Kilograms) g = acceleration due to gravity (metres per second squared) h = height above ground (or lower boundary) (metres)

How do you calculate the minimum initial velocity for a rocket to reach the Moon using the gravitational potential energy equation?
Once you have the gravitational potential energy required to move an object a certain distance away from the Earth, you simply plug it into the formula for the kinetic energy, and solve for speed.
What would be the skaters speed if all the potential energy could be converted into kinetic energy?
Clearly, that depends on the amount of potential energy. If given the height, calculate the potential energy with the formula for gravitational potential energy (PE = mgh). If mass is not given, you can assume any mass (it doesn't affect the result), or use a variable "m". Then, assuming it gets converted to kinetic energy, use the formula for kinetic energy (KE = (1/2)mv2), replace the KE with the energy you calculated before, and solve for v (the speed).

What is the height of 40000 kg exerts an energy of 420 000 J?
Use the formula for gravitational potential energy: PE = mgh Replace the numbers you know: energy (PE), mass, and a gravity of about 9.8. Solve the resulting equation for height. Since you are using standard SI units, the answer will be in meters.
What is the potential energy of an apple is 6 joules the apple is 3 meters high what is the mass of the apple?
The idea is to use the formula for potential energy: PE = mgh. Replace the numbers you know, and solve for the missing number.
How do you solve potential energy?
Kinetic energy is 1/2 x m x v^2 (one half x mass x velocity squared) There are lots of different kinds of potential energy, each kind has its own formula. The one you probably mean is gravitational potential energy. This is m x g x y (mass x acceleration due to gravity x height) or also w x y (weight x height). The height is usually measured from the ground.

When an 8 kg object increases its potential energy by 240 J how much has its position changed?
Just use the formula for potential energy: PE = mgh (potential energy = mass x gravity x height). Use 9.8 for gravity, replace the parts you know, and solve for the unknown position (height).
