Predict: Will a 1500 kg car moving at the same speed as the tennis ball have more momentum or less? (i think more) Calculate the momentum of the car and record it here.

The car will have more momentum because it has a greater mass. Momentum= mass x velocity therefore if both the objects have the same velocity.

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.
