What is the most significant factor in determining kinetic energy?

The velocity

Explanation:

Kinetic energy of an object is directly proportional to the square of its velocity if mass if kept constant. Therefore, if the velocity is doubled the kinetic energy increases four times.

K.E= 1/2mv²

m is the mass of the object and v the velocity. This means that there must be motion for there to be kinetic energy.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
