In a 1.5V battery taking the negative terminal as 0.0V what is the electrical potential energy of an electron leaving the negative battery terminal?
Somebody is trying a trick question! The electron that comes out of the negative terminal has zero potential energy. With respect to the positive terminal it has -1.5V of electrical potential energy, and so does every other electron at 0.0V whether or not they came out of the battery.
How is potential energy created in a chemical cell?
potential energy is created by separating charges with chemical reactions so that one terminal is negatively charged, while the other terminal becomes positively charged.
How is energy conserved when you throw a ball into the air and then catch it?
The summation of potential and kinetic energy is constant
What does the object of potential energy depend on?
That really depends on the type of potential energy - but basically you can calculate potential energy as force x distance. This assumes constant force; if force isn't constant, you use an integral instead.
Where is the maximum and minimum kinetic and potential energy found as a ball drops?
A ball at rest contains only potential energy. A ball in motion contains almost all kinetic energy. But it gets tricky here. A free falling ball that has not yet reached terminal velocity has no potential energy. That energy is being given up to kinetic energy. Once the ball reaches terminal velocity in Earth's atmosphere, air resistance holds back further conversion of potential energy to kinetic.
A battery has a difference in potential energy between the positive terminal and negative terminal which units express this difference in energy?
That's a difference in electrical potential, not potential energy.It's described in units of "volts".
Does A neuron expends energy while it maintains a resting potential?
yes it does

Is it possible for a ball to also have potential energy as it is rolling?
Yes, if it is rolling at a constant speed it has potential energy.

Where is the potential energy in a DNA molecule found?
The potential energy stored in the bonds of the phosphates provides the energy for DNA synthesis.
When a solid moves vertically down a liquid at terminal velocity work done on it is zero but it's gravitational potential energy decreases HOW?
As you say, work is not being done on it and its kinetic energy is constant, but it is losing potential energy. In this case the potential energy loss is being dissipated into turbulence of the fluid, which is a mechanical form of energy, and perhaps some thermal heating due to friction. A good question, made me think!
What relationship exists between height and potential energy if mass is held constant?
Potential energy is directly proportional to height.
The potential energy in ATP is released when the terminal high energy bond is broken by a process called what?
Hydrolysis
Where does the gravitational potential energy go when a parachutist's kinetic energy is constant?
wind resistance
How is energy in potential and kinetic conserved?
For any object, the summation of its potential and kinetic energies is constant.
What is the sum of kinetic energy and potential energies?
Mechanical Energy
