Question

This is a question on my science hw.

Answer 1

I think it is better to prove it,

when you put two things in the same altitude , only when they have the same speed, can fall on the grownd in the same time,

so, we can prove it :

1)we know that the acceleration of the earf (gravity or g)is the same for every thing on it :

we know: V=at +V1 and here it is

V=gt+V1

so Va=Vb because gta +V1a=gtb + V1b

and V1 is 0 =>gta=gtb =>ta=tb

(a and b are names of two assumed things)

Answer 2

gravity is like a gas that sticks us to ground no matter what object is falling they were both fall down at the same time because it doesn't matter the mass it just matters like the curve around them like if the curve and like their sides
