a boulder falling through the air still has some potential energy, but some of its potential energy has changed to kinetic energy...so it has both potential and kinetic!
If the air is moving, then it has kinetic energy. If the fan is running, then the blade has kinetic energy. Maybe that's where the moving air got its kinetic energy from. If the dog is also walking through the room, then the dog has kinetic energy too, but he probably didn't get his kinetic energy from the fan or the air. On the other hand, a piece of tissue floating through the room could very well have gotten its kinetic energy from the fan, but that kinetic energy had to be carried from the fan to the tissue by the moving air.
the air inside the balloon has more kinetic energy
When a soccer player kicks a ball into the air, its kinetic energy is drained through air resistance and by the force of gravity. At its highest point, the ball has all of its vertical kinetic energy converted into potential energy. As the ball falls, this potential energy is converted back into kinetic energy. It should be noted that through the entire process of rising and falling the ball maintained horizontal kinetic energy being dissipated by resistance until it hit the ground and stopped.
it has kinetic energy..because its moving.... kinetic energy is if something moves....thats why its kinetic energy

Kinetic energy is energy in motion. So, there is kinetic energy when the ball is moving through the air. There is sciatic energy when the ball is resting on the racket! Hope this helps.
Kinetic
It turns into mechanical energy-a mass of air is being pushed through the fan so the air molecules are being given kinetic energy (I'm saying mechanical energy includes kinetic energy)

The Ball has energy in the form of potential energy as if it was released it would fall to the ground. The pitcher uses chemical energy to move his arm and give momentum to the ball. The ball's energy is now transformed to kinetic energy as it moves through the air.
kinetic. Vocal Cords vibrate (kinetic energy) causing vibrations to move through the air (kinetic), which cause the ear drum to vibrate (kinetic), which induces electric impulses in the brain (electric).

Sound is a wave in the air which is actually a compressive variation in the air pressure, at the frequency of the sound. So it involves movement of air molecules, and in that sense is kinetic. We usually talk of acoustic energy, which is related to the Sound Pressure Level, which is the physical effect being propogated.
The kinetic energy would be the energy of a piece of snow hurtling through the air. The potential energy would be calculated based on how far the piece of snow has to go to reach the ground.
