The way I was taught my teacher told me that to find the distance an object will travel horizontal can be deduced by d=vit+(1/2)at2. She said this is right because the initial velocity of an object will always be zero since before it is shot, thrown, or whatever it is at rest. She said gravity...

Homework Statement I have this lab and my goal is to find how far I should place a box if I was to catch a plastic leprechaun that weighs 22.4 grams fired out of an air cannon. I did this lab and the final velocity I ended with was 12.76 meters/sec (29.72 meters was the average distance and...

Alright that makes a lot more sense now. Thank you ehild.

Glass is designed to only allow visible wavelength to pass, and once you get to the infrared spectrum glass simply absorbs it. (http://www.dandydesigns.org/id58.html this kinda explains it)

No air will not stop my fist if I was punching the air. However Newton's third law states that every action has an opposite and equal reaction. When I hit the air I am hitting particles in the air and they are hitting me back. Since my body is it's own system and since force is F=ma I can always...

Homework Statement My teacher puzzled me in the beginning of the year by saying that one cannot possible hit a falling feather with 200 Newtons because a falling feather doesn't have 200 Newtons to hit you back with. (Newton's Third Law) Homework Equations None The Attempt at a...

This doesn't prove how or why they are attracted this is only used to find the force due to gravity between the two objects.
