Negative work increases potential energy.
Probably nothing. Potential energy means that it is stored and not being used. It may eventually fall, with kinetic energy, and do some form of work, but as long as it only has potential energy, it remains motionless.
An object's potential energy doesn't depend on its speed. You can do anything you like with the object's speed, and it has no effect on potential energy.
When the membrane potential becomes more negative it is being hyperpolarized. Remember the resting membrane potential is already at a negative state (~70mV). So if you are making a comparison of a membrane potential that is hyperpolarized in comparison to a resting membrane potential, the resting membrane potential is said to be more depolarized.When the membrane potential becomes more positive it is called depolarization.
Yes - mechanical energy includes both gravitational potential energy, and kinetic energy. If an object's momentum is zero, then its kinetic energy will also be zero, but its potential energy can be positive or negative, depending on whether the object is above or below the chosen reference level.
Is it changing from kinetic energy to potential energy
Potential energy is stored energy, that can be released at any time. Also, potential energy is energy of position.
Kinetic energy being converted to chemical potential energy
Energy that is not being used is called potential energy.
The energy that is not being used is referred to as the potential energy.
"Gravitational potential" or just "potential" energy.
