# 2 Physics questions watch

1. Hey, I have a bit of unfinished work from my Physics lesson a few weeks back (I'm going through my folder) however, my mind has gone pretty blank as it was a few weeks ago like I said.
I think I have to put newtons laws into my answers...

1. Explain why a raindrop falling vertically through still air reaches a constant velocity.
It's worth 4 marks. I know that the forces become balanced and blah blah, but I don't know how to get 4 marks? And I think we have to put newtons laws in there aswell.

2. An apple and a leaf fall from a tree at the same instant. Both apple and leaf start at the same height above the ground but the apple hits the ground first. Use Newton's laws of motion to explain why...
i) The leaf accelerates at first then reaches a terminal velocity

ii) the apple hits the ground first
worth 5 marks.

Again I have a rough idea, but I'm unsure how to get 5 marks and how to include newtons laws into the answer.
Thanks!
2. Split it down into each different "phase" if you like, and apply Newton's laws to each of them along with your explanation.
3. Hmm, I still can't really get an answer. Thanks though!
4. You need to talk about the forces acting, how they change an what happens to the resultant force.
