# Newton's Laws - Mission NL4 Detailed Help

 For the following physical situation, identify the forces that are exerted upon the object.   A sledder slows down as it glides into the wind across some unpacked snow.
 Often times, success in physics demands that you have the proper approach - a good game plan. When determining which types of forces act upon an object in a given situation, proceed through the list of forces and ask: Is this force present on the object?    Answering this question demands that you understand each type of force. If necessary, use the link in the Hot Link section below to navigate to a web page that describes each force on the list of force types.
 A physics question often contains a short phrase that might seem a bit peculiar. It is the type of phrase that might cause one to wonder why it is included within the question. In actuality, the phrase serves to provide a hint or clue that might steer you in the right direction. In this question, the clue is in the phrase "across some unpacked snow". Including this phrase in the question warns the student that the snow is not like friction-free ice. Thus, the force of friction should be included in the answer.
