Question

The value of gravitational acceleration (g) is taken to
be -g when studying the motion of an object thrown upwards in
straight line​

Answer 1

Answer:

Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2. When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location. There are slight variations in the value of g about earth's surface.
