Question

A bullet fired from a rifle begins to fall
as soon as it leaves the barrel.
after air friction reduces its speed.
not at all if air resistance is ignored.

Answer 1

@ganeshie8 I have stuck on this for days and dont understand the concept at all

Answer 2

I have been*

Answer 3

gravity pulls everything down

Answer 4

when the bullet is inside rifle, the inter molecular forces of rifle are stopping the bullet from falling down

Answer 5

then wouldnt gravity be pulling it down while it being in the rifle

Answer 6

oh

Answer 7

^ above reply

Answer 8

i think u get the idea :)

Answer 9

Im sorry I dont understand

Answer 10

gravity pulls things down

Answer 11

but I dont understand at what point would the bullet be falling, if its not in the rifle is has to be once it leaves it..right?

Answer 12

ok, answer me this

Answer 13

gravity is pulling that ball down, but its staying on that table. how ?

Answer 14

bc there is a force pushing it up

Answer 15

yup, the tension in the feet is pushing it up.

Answer 16

therefore not all air resistance is ignored? bc air resistance is a force right?

Answer 17

if we go microscopically, we will understand that, there are some inter-molecular forces acting on the solid table, keeping it rigid. and not allowing to gravity to pull the ball down

Answer 18

A bullet fired from a rifle begins to fall
as soon as it leaves the barrel.

Answer 19

as soon as the bullet leaves rifle, the counter force is GONE !
so gravity wins ! and the bullet keeps falling down slowly, inch by inch...

Answer 20

ohh so anything in the air is pulled down by gravity bc there is no opposite force pulling it back?
