The energy associated with a bicycle changes as it speeds up going downhill due to the fact that potential energy is converted to kinetic energy. The potential energy is the energy of the position. The kinetic energy is the energy of movement.
No. Gravity is a force. Potential energy turns into kinetic (moving) energy when you fall due to gravity.
Its a bad example, but some potential energy is involved. You convert chemical energy from the fuel to kinetic energy and heat energy. The kinetic energy drives you into the water. There the car sinks because of the height difference and gravity. This is a form of potential energy. A better example would be a person driving up and down a mountain. When driving up a mountain you store kinetic energy into potential energy. On the way down you regain the potential energy you stored, which results in a higher kinetic energy when driving down.
Kinetic energy is the energy in a mass of matter that is in motion, the energy of motion. Potential energy (where mass is in a gravity field) can be converted into kinetic energy Chemical energy (of an explosion) can be converted into kinetic energy Electrical energy can be converted into kinetic energy (eg in an electric motor)
The situation is similar as when an object falls. Potential energy is converted to kinetic energy (including rotational energy in this case); part of that kinetic energy is converted to heat energy.
it is both kinetic and potential energy
No, it's potential energy turning into kinetic energy.
There is no "gravity kinetic energy". There is gravitational energy (a type of potential energy), and - separately - there is kinetic energy (the energy of movement).
yes because if you were running down a hill you are in motion and kinetic energy is in its greatest coming downhill.
The object can be stationary and have gravity pulling on it ergo no kinetic energy

Gravity is a force more so than an energy
Generally when water is used as a source of energy it is either the kinetic energy of the flowing water or the potential energy of the water as it changed height that was used as the energy source. In both cases it is gravity that is the ultimate driving force that makes the water move (for kinetic energy) or is the source of the potential energy - which is recovered as the water moves from higher to lower.
Water flowing downhill does not require energy, only the force of gravity.
