Answer 1
Kinetic. Remember, kinetic energy is the energy of movement.
Answer 2
If one considers winding up for the pitch as analogous to winding up the spring on a crossbow, then you are converting kinetic energy (the motion produced by your arms) to potential "elastic" energy. Releasing the catch on the bow then converts the stored potential energy to the kinetic energy of the bolt as it flies away.
Of course people are not crossbows, and the interplay of forces and motions is a bit more complex.
Added:
Answer two's analogy is flawed as the potential energy on the cross bow winding is not potential until the mechanism is stopped and locked. Until that point the energy is kinetic to potential. A pitcher winding up does not store potential energy as a locked in place cross bow bolt does.
Added 2:
Hence my statement that winding up a crossbow is *converting* kinetic energy to potential, while releasing the crossbow *converts* potential to kinetic energy.
But as already noted, comparing winding up for a pitch to winding up a crossbow is probably not very accurate anyway.
When a pitcher winds himself up for a pitch, he positions himself in such a way as to be able to convert the maximum amount of *chemical* energy into kinetic energy. At least, that's how I see it.
Wind turbines convert the kinetic energy of the wind into mechanical energy, which is then transformed into electrical energy. They do not convert energy directly back into potential, kinetic, or thermal energy.
Blowing wind has kinetic energy. This can be transformed into electrical energy using a turbine to transform the wind into rotational kinetic energy and a generator or alternator to convert the rotational kinetic energy to electrical energy. Water above a dam has potential energy from gravity and also from the weight of the water around it. Once it is moving or flowing down through the pipes it then has kinetic energy.
potential energy that gets converted into kinetic energy as the toy unwinds and moves. As the spring unwinds, the potential energy is transformed into mechanical energy, causing the toy to move.
Those energy that are not transferred to ATP loss as heat.
The motorcycle's gasoline is potential energy. The energy is released as a chemical reaction (chemical energy) and converted to heat (heat energy). It then becomes converted to kinetic energy with the movement in the engine, and subsequent movement of the motorcycle.
When a pitcher winds up for a pitch, the energy is primarily in the form of potential energy as the pitcher is storing energy in their muscles and tendons. This potential energy is then converted into kinetic energy when the pitcher releases the ball.
Winding up for a pitch involves converting potential energy (stored energy due to position or configuration) into kinetic energy (energy of motion) when the pitcher releases the ball.
Wind turbines convert the kinetic energy of the wind into mechanical energy, which is then transformed into electrical energy. They do not convert energy directly back into potential, kinetic, or thermal energy.

When a pitcher winds up to throw a ball, it is considered potential energy because the motion is being stored as an energy of position before it is released in a kinetic form as the ball is thrown.
A flag blowing in the wind demonstrates kinetic energy, which is the energy of motion. The wind provides the force that causes the flag to move, resulting in kinetic energy being produced.
Wind blowing is an example of kinetic energy, not potential energy. Potential energy is energy stored in an object due to its position or state, whereas kinetic energy is the energy an object possesses due to its motion.
A windmill converts the kinetic energy of wind into mechanical energy through its rotating blades. This mechanical energy can then be further converted into electrical energy, making a windmill primarily a kinetic energy conversion device.
Wind energy is a form of kinetic energy. It is generated by the movement of air molecules, which causes the blades of wind turbines to spin and produce electricity.
Blowing wind is considered kinetic energy. It is the energy possessed by a moving object or particle. In the case of wind, it is the energy associated with the movement of air molecules.
The wind is an example of kinetic energy - the energy of motion. It is generally transferred as kinetic erergy to, say, a windmill where it could pump water and the kinetic energy is converted to potential energy.
No, it falls in the category of potential energy
