Potential energy is the capacity of an object to do work. This can take many forms. Chemical potential energy is a good example - coal doesn't look like it has a massive amount of energy in it, but set fire to it and it burns for hours. The potential energy is stored inside the C-C and C-H bonds within the mixture of hydrocarbons, which are broken in the combustion reaction and then reform in new ways to release that energy.

A box on a high shelf has gravitational potential energy. Anything that is in a field has potential energy due to its position. Work is done against gravity in the Earth's gravitational field to raise the box from the ground to the shelf, and this energy is stored as GPE. When the box is pushed off the shelf and accelerates to the ground due to gravitation, this GPE is converted to kinetic energy mainly. This is the capacity to do work being realised.

A stretched spring also has potential energy. Consider the motion of stretching it with your hands, it involves effort to do so because you are doing work against the restoring force the spring produces due to Hooke's Law (F = -kx, for spring constant k). This work is stored as elastic potential energy, and is released when the spring is released.

In conclusion, both have potential energy. I hope this helps :)

Answer from: Quest

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

Onsider a u-tube whose arms are open to the atmosphere. now, equal volumes of water (ρ = 62.4 lbm/ft3) and light oil (ρ = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and thus the liquid levels in the two arms are the same. if the fluid height in each arm is 31 in, determine the gage pressure the person exerts on the oil by blowing. (round the final answer to three decimal places.)
