Find the kinetic energy, gravitational potential energy, and total mechanical energy at each of the five points listed below using the information provided. A 20-kg ball is dropped down a ramp at position A at a height of 400m. Assume that each position on the ramp is equidistant from the other and that there is no friction. Show your work please!

the pull of gravity on the rocket decreases

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.
