If the weight of an object of 1 kg is 10 Newtons then how does every object fall with the same acceleration (acceleration due to gravity / acceleration of free fall)?
I'm asking this because if every object has a different weight and so exerts a different amount of force towards the ground, wouldn't the acceleration differ for each of the objects?

Answer:
obviously yes, because every has not same acceleration which works in gravity
Answer:
(THIS IS ONLY APPLICABLE UNDER CONDITION OF FREE FALL)
This is because, regardless of their respective weight, they fall with same rate i.e. acceleration due to gravity....
Explanation:
Let's take two examples, a ball of mass 1 kg, falling with a force of 10 Newton, and second call of mass 2 kg, falling with a force of 20 Newton..
Here if on object he twice mass, Earth has to pull with twice force, which will in turn pull the objects downwards with same rate, According to The Second Law Of Motion,
F=ma (here you'll take a = g = 10 m/s^2)
Hence,
- Case 1. Ball of mass 1 Kg
F=mg
10 = 1 × g
g = 10 / 1 i.e. 10 m/s^2
- Case 2. Ball of mass 2 kg
F=mg
20 = 2 × g
g = 20 / 2 i.e. 10 m/s^2
Conclusion: Hence, you can see that the acceleration due to gravity in both Case. 1 and Case. 2 comes out to be 10 m/s^2, hence a pull of same rate will be exerted, hence irrespective of weight of any body that free falls, the acceleration due to gravity will be same......
