Best ResponseYou've already chosen the best response.2If we neglect air resistance, the only force acting on the ball after it's released is gravity, which is a constant downward force. So, as the ball is travelling upward the velocity decreases since the force acts opposite to its direction of motion. The acceleration remains constant as the force and mass are constant.

Best ResponseYou've already chosen the best response.0The ball is thrown upwards, it's velocity decreases until the highest point where it can reach where it's instantaneous velocity becomes 0 for a moment and as it comes down, it's velocity increases, acceleration remains constant since the force with which it is thrown and its mass remain the same.dw:1329738443479:dw

Best ResponseYou've already chosen the best response.0The velocity decreases as the ball moves upwards because the force of gravity (g=9.8 m/s^2) is acting against it, and increases as it's coming down since in is in the same direction as the gravitational force, and thus gets added up.
