1. Does a force applied to an object always produce motion? What can you figure out about the forces on an object just by observing its motion?
2. When you are a passenger in a car that makes a tight turn, your body seems to respond to the turn by moving towards the side of the car on the outside of the turn. Is a force acting on you that pushes you towards the outside of the curve? Explain. Consider the message of Newton's First Law in your answer.
