Want this question answered?
The potential energy is 147 joules.
the box when it is inclined will have greatest potential energy on the top corners only.
This box has potential energy of 98 Joules.
Potential chemical energy
The potential energy of the box on the ground is considered to be zero. Potential energy is the energy that is stored within an object due to its position or state. Since the box is already at ground level, it does not possess any potential energy.

Nothing really causes potential energy as it is merely just energy in storage. For example, water has energy in its chemical bonds, but the potential energy will only be released when the bonds are broken.
Picking up the box gives it kinetic energy. When the box is sitting on the shelf, it has potential energy.
No. A spring has ANOTHER kind of potential energy.
A box of matches on a high shelf has gravitational potential energy.A box of matches falling from the high shelf has kinetic energy.A box of matches on fire has heat, sound and light energy.A box of matches on its own has chemical potential energy.
Are you referring to the biological energy transformations involved in the body of a person actually lifting a box? Or are you referring to the act of imbuing an inanimate object with potential kinetic energy? If it is the latter; You are investing Potential Kinetic Energy in the box when you put it up on a shelf. If your body were 100% efficient, it should have expendeded as much energy in raising the box as the box then possesses. Because the box can fall, it will have the potential to transform its potential kinetic energy into actual kinetic energy, by virtue of its mass and velocity. It could do work, like falling on a lever which propelled a weight up a column and rang a bell on the top. If it is the former... I don't know.
Gravity-potential energy
The work done is stored as potential energy of the box P=Mgh F=Ma (a=g) F=Mg h=5m Therefore the work done is 20*5 = 100 joules -----------------------------------------------------------------------------------------------------
