When a ball is dropped

oh i think i got it guys:)

when the ball is falling, acc is cont...and when the ball bounces off the floor...the acc is still const...but since takin downward motion as positive...the acc is positive...

but at the instant at which the ball hits the ground....the acceleration falls...
but parth dave why does the acceleration fall at the instant at which the ball hits the ground?

so i realise everytime at the instant the ball bounces...the acceleration falls...by less and less...

but why does the g fall to a neg value when the ball hits the ground? i cant see what the compression of the ball has anything to do with the acc...help plzzzz

and thanx for all the replies:)
