when a ball is thrown upward there will initial speed let it be ""u"".
the gravity will act on the ball when it goes up and comes down.
the velocity of ball becomes zero when it reaches maximum height. Then the only force acts on the ball at this moment is gravity .
the ball accelerates downwards with 9.8m/s² .
The force acting downwards when ball moved up is ""-mg"",-ve sign indicates the motion of ball is opposite to the force acting downward and ma is force acting upwards .
when ball comes down the only force is mg (+ve)
