If the numerical value of acceleration due to gravity at a place is 9.8, what are its units?
The unit of 'g' is m/s2.
Does the gravitational force between two bodies depend upon the presence of other bodies in the surroundings?
No, gravitaional force does not depend upon the presence of other bodies in the surroundings. It remanins constant.
Define acceleration due to gravity.
An object which is falling freely under the effect of gravity gets accelerated. This acceleration is called as 'acceleration due to gravity'.
Do all bodies fall with the same acceleration in the absence of air resistance?
Yes, all bodies fall with the same acceleration in the absence of air resistance and this acceleration is called 'acceleration due to gravity'.
