Question

vertically projected body acceleration due to gravity ’g’ is taken as
OPTIONS
1) positive
2) negative
3) zero
4) infinity​

Answer 1

ANSWER:

2) NEGATIVE

EXPLANATION:

Generally, the positive direction is assumed to be of the direction of motion and rest of the parameters are adjudged by direction of motion. So, if an object is moving vertically upwards, the direction of motion is positive for upwards joirney. Hence, the acceleration due to gravity is taken as negative as its direction is downward.
