people who are good at physics

<p>Alright. We got this extra credit assignment from physics class. And basically we are supposed to build a parachute using plastic bag with an egg attached to the strings that are attached to the parachute. And our physics teachers is going to stand on the roof of the school building and throw it out to see if it works fine. And when it lands on the ground without the egg breaking, we get full credits. Okay, so you get the idea. </p>

<p>We got the parachute and all. But we are struggling on the research work.</p>

<p>I need to know things like "physics" behind this parachute. Any information relating to physics that can understand how this parachute works. Can someone help me out?</p>

<p>One way to protect the egg is to slow it down by increasing the amount friction with the air. This is how a parachute works. You can also work on designing a container that has rough surfaces so as to increase air resistance.</p>

<p>wow thanks that's a great help. Can you give me more facts?</p>

<p>yeah, drag force is proportional to the cross sectional area so make sure the parachute has a relatively big...cross sectional area :/</p>
