Question

What is the value of ‘g’ when a body is thrown vertically upwards?

Answer 1

1. When a body is thrown vertically upwards, then its velocity decreases.
2. The acceleration due to the gravity of the body is constant i.e. $9.8m{s}^{-2}$.
3. The displacement that takes place in the upward direction is positive thus, the value of acceleration due to gravity is negative.
4. Thus, the value of acceleration due to gravity is $-9.8m{s}^{-2}$.
