Answer :
When air is totally removed and 2 bodies of different masses are simultaneously made 2 fall from d same height, they will reach d ground simultaneously. Thus, all bodies travel the same distance in d same time interval of time in vacuum. N
Acceleration due 2 gravity does not depend on d mass of a body bcz the aaceleration due to gravity is same for all bodies and it is uniformly accelerated.
Acceleration due 2 gravity does not depend on d mass of a body bcz the aaceleration due to gravity is same for all bodies and it is uniformly accelerated.
1) If air is totally removed in the space where two bodies of different masses are falling, then the air resistance faced by the bodies is zero. The acceleration due to gravity is the acceleration of the two bodies towards the ground. Same initial speed and same acceleration, so the bodies fall simultaneously.
When air is present the bodies face different air resistances (buoyancy forces), so their accelerations are different and less than g.
2) Acceleration due to gravity g = G Me /Re² where G = gravitational constant, Me is the mass of Earth and Re is radius of Earth. It comes to 9.8 m/sec². It does not depend on the mass.
g = weght /mass = gravitational force / mass
= GMm/d² / mass = G Me / Re²
