The potential energy can be exactly defined as the work required to place an object into a certain position - which is the integral of the dot product of force and displacement. In the case of gravitational potential energy, and for small differences in altitude (so that gravity doesn't change too much), that simplifies to mgh (mass x gravity x height).

What has more potential energy a 50 kilogram stone or a 70 kilogram stone?
Both of them equal energy. Potential energy = mgh = 100*9.8*1 and 50*9.8*2 are equal.
How do you calculate an objects mechanical energy?
An object's mechanical energy is the sum of the potential and kinetic energy it possesses.
What professions calculate mechanical energy?
by adding potential energy and kinetic energy, you get mechanical energy.
What is the formula of gravity potential energy?
PE = mgh (potential energy = mass x gravity x height).
What is the formula for calculating mechanical energy?
Mechanical energy is the sum of potential energy + kinetic energy.
The formula Weight x Height is used to calculate what kind of energy?
Relative gravitational potential energy.
Does gravitational acceleration calculate potential energy?
Gravitational potential energy describes how much energy a body has in store by virtue of having been elevated to a specific height. The formula to calculate gravitational potential energy is:.U = mgh.Where:U is the potential energym is the mass of the objectg is the acceleration due to gravity, andh is the height the object will fall if dropped.
How do you calculate change in potential energy?
more often than not, potential energy is calculated, not measured, based on which means of energy conversion you are looking for. Potential energy released by falling is not the same as potential energy of a nuclear reaction, although the same object can do both
What is the proper formula to calculate potentialenergy?
potential energy = mass x acceleration due to gravity (9.81m/s2) x height
How do you find the gravitational potential energy?
Gravitational Potential Energy is equal to Potential Energy therefore the formula for GPE (Gravitational Potential Energy) is PE=mass x gravity x height therefore the formula is PE=mgh
How is the height of an object related to its potential energy?
The formula for potential energy is: G.P.E. (gravitational potential energy) = Weight x Height
What would be the skaters speed if all the potential energy could be converted into kinetic energy?
Clearly, that depends on the amount of potential energy. If given the height, calculate the potential energy with the formula for gravitational potential energy (PE = mgh). If mass is not given, you can assume any mass (it doesn't affect the result), or use a variable "m". Then, assuming it gets converted to kinetic energy, use the formula for kinetic energy (KE = (1/2)mv2), replace the KE with the energy you calculated before, and solve for v (the speed).
Formula for total energy?
kinetic energy+potential energy=total energy
What has more potential energy a 50 kilogram stone or a 70 kilogram stone?
Both of them equal energy. Potential energy = mgh = 100*9.8*1 and 50*9.8*2 are equal.
How do you calculate an objects mechanical energy?
An object's mechanical energy is the sum of the potential and kinetic energy it possesses.
How much electrical energy is required to move 4.00 mC of charge through a potential difference of 36.0 V?
0.144 JOULES. One can calculate this from the formula E=Vq in which E is energy, V is potential difference & q is charge.
What professions calculate mechanical energy?
by adding potential energy and kinetic energy, you get mechanical energy.
