Now, assume two objects are dropped from the same height, but at different times. As they drop, do they get closer together, farther apart, or maintain the same separation distance? Why? (Assume neither reaches terminal velocity.)

'A skydiver jumps out of a hovering helicopter: A few seconds later; another skydiver jumps out, so they both fall along the same vertical line relative to the helicopter: Assume both skydivers fall with the same acceleration. How does the vertical distance between them change? increases decreases stays the same How does the difference in their velocities change? increases decreases stays the same'
In the absence of air resistance, all objects dropped near the Earth’s surface accelerate at the same rate. If two similar objects are dropped, one a short time interval Δt after the other: a) What can you say about the relative speeds of the two objects at any instant after both objects are in free fall? In other words, will ball B be moving faster, slower, or at the same speed as ball A? Why? b) What happens to their separation distance at any instant after both are in free fall? Will it increase, decrease, or stay the same? Why? c) How does the time interval between the impacts of both objects compare to the time interval between their drop times? Will it greater, less than, or the same? Why?
