It is released (it has been stored in the spring) and appears as kinetic energy
potential energy changes to kinetic energy
It's potential energy decreases.
Then part of the potential energy will either remain as potential energy, or be converted into some other type of energy.
Yes, it is based on both. Potential energy (gravitational potential energy, to be more precise) is simply the weight multiplied by the height.
They lose potential energy.
we release the potential energy to heat energy to do work
Potential energy is unrelated to speed.
Potential energy will decrease.
Potential energy is not affected by speed.
If potential energy is not converted into kinetic energy (or into any other type of energy) then it remains potential. Potential energy does not expire.
potential energy changes to kinetic energy
It's potential energy decreases.
The potential energy of the molecules change during a reaction.
The potential energy of the molecules change during a reaction.
The potential energy is transformed to heat or light energy
Negative work increases potential energy.
Its potential energy increases as it regains its shape.
