A ball is tossed vertically upward and caught at the position from which it was released.
• Ignoring air resistance will the ball at the instant it reaches its original position be traveling faster, slower, or at the same speed as it was when released?
answer/question/discussion: ->->->->->->->->->->->-> :
The ball will be traveling at the same speed at its time of release and when it falls back to that initial position.
• What, if anything, is different in your answer if air resistance is present? Give your best explanation.
answer/question/discussion: ->->->->->->->->->->->-> :
However, if air resistance is involved, when it is falling back down, it will be going slower. This is because it will lose energy. The reason they would be traveling the same speed in a vacuum, is because the energy is conservative, but when friction is involved, some energy is lost.
