Since potential energy equals mgh. When h, height increases potential energy also increases. If h is 0 then p.e is 0/
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)
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.
"Gravitational potential" or just "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 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.
0!!! No change as gravity is a constant factor!!

There are several different varieties of potential energy, some of which involve position and some of which don't. Gravitational potential energy involves position. High objects have the potential to fall.
By using chemicals in a rocket engine to raise a vehicle high above the earth's surface, the vehicle will gain gravitational potential energy. It will also gain kinetic energy, depending on what trajectory it follows
If an object is above ground level, it has positive gravitational potential energy. (This assumes you define ground level to be zero - actually, you can define any level to be zero.)
No. For example, a satellite in orbit has a lot of both.
The hammer will have potential energy. It is because of the height.
If an object - in this case the high diver - is above the reference level, then its gravitational potential energy will be positive.Note that the reference level is arbitrary, but quite often, the ground level is chosen for calculations of gravitational potential energy.
