Which of the following is incorrect about acceleration?
(1) It is a vector quantity
(2)It may be positive, negative or zero
(3)It's unit is m/s2
(4)The slope of displacement-time graph gives
acceleration​

Answer 1

Answer:

the answer is D) the slope of displacemcemt- time graph gives acclerationh

the slope of the displacement-time graph gives velocity

accleration is give by the slope of the velocity-time graph
