Explain the velocity of the objects in terms of air resistance.
Explain the velocity of two different objects: heavy rock and light feather. First, explain what happens while the two objects are dropped on Earth. Second, evaluate this to what happens on the Moon (make sure to refer to the movie found on the web site which shows a NASA astronaut doing this experiment on the Moon). Finally, find a cotton ball and rock that are about the same size and drop them. Then place them in two boxes with the exact same size, shape, and material. Drop them again. What do you find? Explain your findings in terms of air resistance before placing the objects in the container and after placing those in the container (i.e. try a cylindrical 35mm film holder).
Heavy rock and feather dropped on Earth explanation.
Heavy rock and feather dropped on Moon description.
Activity and description of rock and cotton ball dropped on Earth. First drop them. Then drop them in the same size container. Make certain to explain your findings in terms of the effect of air resistance.
