Scientific Answer As potential energy = Mass x g x Height
Mass = 1 kg
g = 9.8 m/s2
Height = 2 m
PE = 1 x 9.8 x 2
PE = 19.6 Joules On a lighter note The potential energy of a one kg (2.2 lb) box of chocolates hidden on a shelf in pantry two meters (2.18 yds) above the floor is inversely proportional to the combined age and weight of the person trying to find the chocolates. This may be represented by the formula, G=mc2, where "G" represents "Greed" being equivalent to the mass ("m") of the individual multiplied by the weight of the chocolates ("c") squared (2).

∙ 13y agoUse the formula for gravitational potential energy: PE = mgh (mass x gravity x height). Since you are using SI units, gravity is 9.8 meters/second2.

What is the definiton of gravitational potential energy?
Gravitational potential energy is a type of energy that an object possesses because of where it is placed in a gravitational field. The higher the object the more energy it has, so if you had an object that was on the ground and then you put it on a high shelf then it would have more energy when it is on the shelf.
What is the potential energy of a 5 kg object sitting on a shelf 3 m high?
PE = m x 9.8 x h:So, 5kg x 9.8 x 5m = 245 joules potential energy.
When does an object have gravitational potential energy?
Well gravitational potential energy is potential energy that depends on the height of an object so an object would have gravitational potential energy when ever it's of the ground or at a high height (it doesn't have to be very high) for example if you lift up a ball it has the potential to fall or if your climbing a mountain you have gravitational potential energy.
Do a stretched spring and a box on a high shelf both have potential energy why or why not explain you answer?
yes because is more
What kinda of energy is a box of matches?
A box of matches on a high shelf has gravitational potential energy.A box of matches falling from the high shelf has kinetic energy.A box of matches on fire has heat, sound and light energy.A box of matches on its own has chemical potential energy.

Is Book on a high shelf chemical or potential energy?
Potential energy.

PE = m x 9.8 x h:So, 5kg x 9.8 x 5m = 245 joules potential energy.
Why does a book on a high shelf have more potential energy than on a low shelf?
Since potential energy equals mgh. When h, height increases potential energy also increases. If h is 0 then p.e is 0/
What form of stored energy does a book have while it is still on a high shelf?
How does a book on a higher shelf have more potential energy than a book on the lower shelf

What is the mass of a book on a 2 meter high shelf with 20 joules of potential energy?
10

What sort of energy does a book have if it falls off a high shelf?
Before it falls it has gravitational potential energy. While it falls, the potential energy gets converted to kinetic energy. Part of this gets dissipated by friction - mainly converted to heat. Once it hits the ground, all the energy will be converted to heat.
What happens when an object at a high elevation loses height?
Loosing potential energy is stored as kinetic energy.
