Hi

i think the the graph for acceleration in sixth picture is wrong because at the maximum height the acceleration will be zero and when the object is falling acceleration is positive........ i have made the graph see picture below

As it goes UPWARDS it -ve since it's OPPOSING the direction of gravity , and then when it
s going DOWNWARDS it's +ve since it's in the direction of gravity.

ALL together *based on what my teacher said* it's NEGATIVE , and hence it's NOT what you have drawn mate ;)

That's correct. :D

The acceleration is always negative and never becomes zero in this case.

This is because whether the object is going up or down, the acceleration is always negative as it is always directed towards the Earth.  ;)
