Question

1. The ball is thrown up, the value of ‘g’ will be

a. Zero

b. positive

c. negative

d. negligible​

Answer 1

Answer:

c

Explanation:

we take upward direction to be  positive by convention then gravity is acting downward so g will be negative

Answer 2

Answer:

When a body is thrown upward its velocity keeps on decreasing because of the deceleration due to acceleration due to gravity (g) which pulls the body in downward direction. At the maximum height velocity becomes zero.

Therefore, velocity at the top is zero and acceleration is acceleration due to gravity (g).
