Kinetic energy is the energy of mass in motion. The kinetic energy of an object is the energy it has because of its motion. As the speed of the fan increases, so does the kinetic energy, then it transfers energy to the Cup ascent.
Kinetic energy is energy in motion (movement). Energy transfer is the process by which energy is relocated from one system to another, for example, through the transfer of heat, work or mass transfer. (Not really sure what the question this)
