Since air is comprised of molecules that are in constant motion, the air would automatically have kinetic energy on the molecular level. On the macroscopic level, if the air is in motion (such as wind) then it would have kinetic energy by virtue of being mass in motion.
Yes, moving air contains kinetic energy because the particles within the air are in motion. The faster the air is moving, the more kinetic energy it has.
If the feather is moving, it has kinetic energy. If there is room beneath the feather for it to fall, it has potential energy due to gravity.
Wind is moving air. So it contains kinetic energy
It contains kinetic energy mainly. Potential energy is relative to its position
A leaping frog is an example of kinetic energy. Before the jump, the frog contains potential energy. When it jumps, the potential energy converts to energy of motion, otherwise known as kinetic energy.
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.
A moving car has kinetic energy due to its motion.
The kinetic energy of air inside a balloon is higher than that of the outside air because the air molecules in a confined space have more motion due to compression. When the balloon pops or deflates, the high-energy air inside will quickly mix with the lower-energy outside air, equalizing the kinetic energy.
The boulder falling through the air has kinetic energy. This is the energy possessed by an object in motion.
It has kinetic energy because it is moving. Just because it is in the air doesn't mean that it can't have kinetic energy.
Stored mechanical energy can be in the form of both kinetic and potential energy. For example, a wound-up spring contains stored potential energy, while a spinning flywheel contains stored kinetic energy.
Temperature measures the average kinetic energy of air molecules. As the temperature increases, the molecules move faster and have higher kinetic energy.
