Question

When a body is going upwards vertically the acceleration due to gravity is taken as

• A. Positive
• B. Negative
• C. Both A and B
• D. Uncertain

Answer 1

The correct option is B Negative

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.
