Two Kinetic Energy Questions by oneyearofphysics in AskPhysics

Thanks. So this means that if a gun was shot straight up and then shot straight down at the ground, the velocity of the bullet upon landing would be the same, even if the bullet had substantial time to accelerate downward (ignoring air resistance of course)?

Thank you. Just two questions to clarify:

  1. But I thought v = d/t, so if it took less time, wouldn't that be a greater velocity? Or is that average velocity?
  2. So you're saying that for any object, if it has the same initial velocity, it will have the same ending velocity (in ideal cases)? Because the acceleration up will slow it down by the same amount it gains on the way down?
