Making Wind Karts : Forces and Motion

Today at Science, we are tasked to make a wind kart that will travel the furthest. This means that air will be able to make the kart move. The material we had is cardboard, string, and tape. The purpose of this activity is to learn about balance and unbalance forces. When forces of an object are balanced, it will be moving at a constant speed or not moving at all. However, if the forces are unbalanced, the object is either accelerating or decelerating.
