Well, honey, that book on the high shelf has more potential energy because it's got farther to fall. Gravity's just itching for the chance to show off its power and send that book plummeting down to the ground. So, the higher the book, the more potential energy it's got stored up just waiting to be unleashed.
The idea is to use the formula for potential energy: PE = mgh. Replace the numbers you know, and solve for the missing number.
there is no such things as a mass x distance formula. mass x acceleration = force mass x velocity = momentum mass x gravity x height = gravitational potential energy mass x velocity-squared x 1/2 = kinetic energy mass x distance = don't take physics in high school!
Work = (force) x (distance) = (mass) x (gravity) x (height) = (70 x 9.8 x 5)Power = work / time = (70 x 9.8 x 5) / (9) = 3811/9 watts = about 0.51 horsepower.Actually, that's the rate at which his gravitational potential energy increasesas his altitude increases, but in order to accomplish it, he has to generateand expend energy significantly faster than that.
Energy = Work = (force) x (distance) = (250) x (40) = 10,000 newton-meters = 10,000 joulesPower = energy/time = 10,000 joules/2 seconds = 5,000 watts = about 6.7 horsepower (rounded)
"Gravitational potential" or just "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.
It isn't. Voltage can be compared to the GRAVITATIONAL POTENTIAL, which is a concept that is related, but different from, gravitational potential energy.Voltage is the energy change PER UNIT CHARGE between two points. Gravitational potential is the energy PER UNIT MASS between two points.
Gravitational potential energy itself is not dangerous. However, if a system with high gravitational potential energy, such as a large boulder on a hill, were to suddenly release that energy (by rolling down the hill, for example), it could be dangerous to anything in its path.
Potential energy, specifically gravitational potential energy, since the book has the potential to fall due to gravity when it is on the high shelf.
An object at a high altitude has the most gravitational potential energy, as potential energy is directly related to an object's height above a reference point. The higher an object is lifted against gravity, the more potential energy it has.
A tall object, such as a heavy object on a high shelf, has gravitational potential energy that could be dangerous if it were to fall. If the object were to fall, it could cause serious injury to anyone in its path due to the transfer of its gravitational potential energy into kinetic 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.
The two main properties that determine an object's gravitational potential energy are its mass and its height above a reference point, such as the ground. The gravitational potential energy of an object increases with its mass and how high it is raised above the reference point.
There would be more gravitational potential energy than kinetic energy when an object is at a high elevation or position above the ground, where the gravitational potential energy is proportional to the height of the object. As the object falls, the potential energy is converted to kinetic energy, so at any point during the fall, the sum of potential and kinetic energy remains constant.

Gravitational potential energy is directly related to an object's height above a reference point, such as the ground. It is the energy stored in an object due to its position in a gravitational field. The higher an object is lifted, the greater its gravitational potential energy.
