Question

A 100g object is falling freely under gravity in absence of friction what will be the net force on it after 2 seconds?

Answer 1

I tried this....

Explanation:

I would say (because of the absence of friction):

`F=mg`

representing the Weight `W` of the object:

`F=W=0.1*9.8=0.98N`

The only possible difference could be a different value of `g` due to the height BUT in the problem it is not possible (I think) to detect this.
