    Survey for School Project

    Thanks for all the responses guys, it's really helping a bunch. The range of data I'm getting is helping to smooth out the fact about 45% of my responses were from only a select group of people, the people directly in my vicinity. Anywho, thanks again guys. If more people want to continue to...

    Survey for School Project

    If there is some way to convert Canadian grades into a United States GPA metric, then it is not only limited to the United States.

    Calculating Speed of Falling Banana - Just Before it Hits Ground?

    thebigstar25 is correct, this is all about Conservation of Energy. Potential Energy at the start is equal to the Kinetic Energy at the bottom. And since you know the Force and Acceleration, you can figure out Mass. (F=ma) Then just plug it into the equation for PE (PE=mgh).

    Introduction to VECTORS

    Try thinking in terms of the real world. If you are walking at 15 mph, and a 3 mph gust of wind hits you from the front, do you feel more resistance or less (ie, would you add the 3 mph or subtract it)?
