If one were to fire a rifle from the top of a large building( or ballon, or something really high) straight down, would the bullet continue to accelerate, slowdown or what during its decent? |

shot from 100000ft with little air restance yes as gravity would gain 9m per second per second untill drag would slow it down. Shooting that rabbit from the balcony would have no gain but would slow down due to drag and you would not se anything different if you cronied it as it would be in the SD range |
And if it's initial velocity were greater than terminal velocity, it would accelerate (backwards from the direction of travel, or "decelerating" from common point of view) until it slowed to terminal velocity, or until it hit the ground first. Jim |
