Physics · Acceleration due to gravity and its variation with altitude and depth
The centre of gravity of an object is whether it is placed near the surface of t
The centre of gravity of an object is whether it is placed near the surface of the Earth or near the surface of the Moon.
- A. same
- B. different
- C. depend on the situation
- D. none
Step-by-step solution
The center of gravity of an object is the point where the total weight acts. Near the surfaces of Earth and Moon, the gravitational fields are approximately uniform, so the center of gravity coincides with the center of mass, which is a fixed point in the object. Therefore, it remains the same regardless of which celestial body it is near.
