Think back to when you were a kid riding in the backseat of the car. Maybe you once had a milkshake in your hand when your mom hit the brakes. You were secured by your seat belt, but you jerked forward and the milkshake splashed all over the front seat...and your mom. That situation probably never happened to you. But think about something that has happened to you physicallya fall, a jump, an accident, or something you may have done hundreds of times in your favorite sport. Analyze the action and describe it in terms of Newton's laws. Identify the initial conditions and the forces involved. If the action is a sequence of events, analyze it step by step. The more complex the sequence of events, the better!
