Why does a book on a high shelf have more potential energy than on a low shelf?
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.
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.
What is the formula for mass x distance?
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!
How much power must the legs of a 70-kg man develop in order to run up a staircase 5 m high in 9 seconds?
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.
How much power does it take to lift 250 N 40 m high in 2 sec?
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)
Which energy stored by being high up?
"Gravitational potential" or just "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.
How is voltage similar to 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.
Can gravitational potential energy dangerous?
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.
What form of stored energy does a book have while it is still on the the high shelf?
Potential energy, specifically gravitational potential energy, since the book has the potential to fall due to gravity when it is on the high shelf.
What has the most gravitational potential energy?
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.
What is a situation in which gravitational potential energy might be dangerous?
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.
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 properties of an object determine its gravitational potential energy?
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.
Why would there be more gravitational potential energy than kinetic energy?
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.
What is the Gravitational potential energy of a 0.25 apple if it is in a tree 8.5 m high?
20.825
What is potential energy that is directly related to how high an object is?
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.
