gravity
your hand

I think 1. is opposite and 2. is gravity but I just want to make sure.

Answer 1

i woudl say reaction force for 1

Answer 2

Well in my text book it says that forces always have equal but opposite pairs.

Answer 3

So wouldn't it be that every force has an opposite force?

Answer 4

ok true, but when I learned physics they called it a reaction force.
if your book says opposite force, then go with that.

Answer 5

Ok, I just wanted to make sure though because this is my last exam . Also, do you agree that 2. is gravity?

Answer 6

why are you saying not your hand?

Answer 7

Because it's saying "As the ball leaves your hand".

Answer 8

So wouldn't it be not counted as a force because it's not acting upon it?

Answer 9

The only force that would be acting on it would be gravity as it's going up in the air.

Answer 10

yeah that's exactly right

Answer 11

Ok, thanks for the help. :)

Answer 12

opposite

Answer 13

Based on Newton's Law equal and opposite forces.

Answer 14

That's what I though also. I also decided to go with gravity and your hand for 2. and I got both of them right. :)

Answer 15

As the ball "leaves" your hand... hmm, that's really trick and wow okay that's great!!!

Answer 16

Lol, thanks for answering though! :)

Answer 17

And yes, number 2 was tricky. :P
