Kinetic energy is anything that was in a resting position and is now moving. The resting position it is in is called gravitational potential energy.
The potential energy of the object can be calculated using the formula: potential energy = mass x gravity x height. Since mass is not provided, we cannot determine the exact potential energy.
If the object is placed at height, it has potential energy and when this object falls down, this potential energy is converted to kinetic (kinesis means movement) energy. If we have to lift object at height , we have to spend energy, witch is released during fall of the object. Example is when water comes down in hydroelectric power station potential energy is converted into kinetic energy. Witch is used to rotate wheel, creating electricity.

First, energy sources are usually split into kinetic and potential. Kinetic energy is the energy of something in motion: the earth in orbit about the sun has kinetic energy. The earth also has kinetic energy due to its rotation. The moon orbiting the earth has kinetic energy, but the moon does not rotate. A car zipping along the highway has kinetic energy as does a train moving on a track. Potential energy is something which can become energy. A rock resting on top of a building can fall off the edge and gravity will pull it downward faster and faster. We say it had potential energy on top of the building's gravity well and this became kinetic energy as it fell. When the rock strikes ground, its kinetic energy will convert to thermal energy warming it and the earth beneath it. Other forms of potential energy include water held by a dam, a gas which has been compressed, and chemicals which can react, such as chemical batteries.

No there is a range of resting potentials. For example retinal ganglion cells have a resting potential of -65 mV while the endocochlear potential is +80 mV.
exhibit a resting potential that is more negative than the "threshold" potential.

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.

The resting membrane potential is maintained by solely by passive transport processes.
The resting membrane potential of a typical neuron is around -65mV
Neurons have a resting membrane potential of approximately -70mV. Muscle cells have a resting membrane potential of approximately -90mV.
