Try this simple air-resistance experiment on your own, and imagine what it might be like to skydive. Stick your hand out the window when riding in a car (watch out for trees). Feel the air pushing against your hand. The faster the car, the more air resistance there will be on your hand. Remember that any force is an interaction between two objects. Not only is the air hitting your hand, your hand is hitting the air. Close your hand into a fist. What changed? Is there less force on your hand? Try it while holding a variety of objects (but be safe!). Record your observations. R search Projects: Readers are pointed toward areas of further inquiry connected to each chapter.
