A ball is bounced. Vertical motion of ball is affected by (1), that is its (2). When it rises it has the vertical deceleration of (3) which (4. slows it down/ speeds it up) and when it falls it has an acceleration of g which (5. Slows it down / speeds it up). The ball's (6) motion is unaffected by gravity. In absence of air resistance, the ball has constant velocity in (7) direction.
