QuestionHow do I calculate the height using this formula?Community AnswerYou can multiply the mass by the gravity, all divided by the GPE. That will give you the height.

QuestionI got 9.81. What was my mistake?Community AnswerIf you followed the instructions above and performed the same calculations only to get 9.81, then you simply entered a number into your calculator incorrectly, so some math went wrong along the way. The number 9.81 in this situation represents the average gravity of earth.

QuestionWhat is energy measured in?Community AnswerEnergy is measured in joules (J). If it reaches a thousand joules, you can convert it into kiloJoules (kJ).

QuestionHow do I calculate the potential energy of a seven-kg object five meters from the ground?Community AnswerHere, you can follow the same rule of mass x gravity x height = universal gravitational. Your equation would be 7 x 9.81 x 5, which equals 343.35.

QuestionHow can I change potential energy into kinetic energy?Community AnswerPotential energy is stored energy, so if a person is still they have potential energy, but when they move or do work, the energy becomes kinetic energy. Anytime you move yourself, or any object that is sitting still, you are changing potential energy to kinetic energy.
-
QuestionWhat are some examples of potential energy?Community AnswerPotential energy is energy that is stored by a body. You can have a potential form of basically any sort of energy. Some examples include gravitational potential energy, elastic potential energy, and electric potential energy.

QuestionHow do I calculate GPE if the mass is in Newtons?Community AnswerOne newton is equal to 0.101972 kilograms, so multiply the value for Newtons by 0.101972 to find your mass in kilograms.
-
QuestionHow do I find the mass and potential energy?LeChatNoirCommunity AnswerCurrently, it's not possible to calculate the amount of potential energy without the mass. If you can find the mass of the object on the internet, you can then follow the above steps to calculate the potential energy, or weigh it if you have a scale.
-
QuestionWhat if the mass was missing?Community AnswerAs long as you have the GPE, the height, and the gravity, you can also calculate the weight and (vice versa). However, if you don't have the mass or the GPE, then you don't have enough information to solve the equation.
-
QuestionHow do I find the GPE at the maximum height of lift if I know the weight of an item and how much work was done to the item?Community AnswerThe amount of work is not always needed. If you know the height and weight, then you can multiply them together and then multiply again by 9.8 (gravitational acceleration). Also, make sure the height is in meters and the weight is in kilograms.

QuestionHow do I find potential energy of something when I know the mass and height?Community AnswerYou can find it with the formula GPE = M x g x h, where M is mass of the object, g is gravity, and h is height.

QuestionHow do I find the GPE of an item if it is on the ground?Community AnswerIf an object is resting on the ground, its GPE is 0. It's that simple. It simply can't fall any further.
