Example text

Component becomes smaller. This relationship is illustrated in Fig. 3 at the beginning and near the end of a poling action. Forces affecting skiing Skier-generated reaction forces at the poles and skis are a competitor’s primary means of moving down the ski tracks. However, several other forces also affect the motion. Gravity is a large force which is determined by a skier’s mass and which is always directed vertically downward. On downhills, a proportion of the gravity force (or weight) of the skier is aimed in the forward direction and acts to propel a skier down the slope.

6 can be grouped into those directed horizontally and those directed vertically. In the horizontal direction if we consider the skier’s forward direction as positive, the horizontal pole reaction force is + 63 N while all the other forces are 26/07/2002 Page 36 CHAPTER 2 negative: air drag force (– 10 N); snow drag force (– 50 N); ski reaction force (– 44 N). Newton’s second law tells us that the sum of these horizontal forces determines the skier’s horizontal acceleration at this moment of time.

What would happen? The two forces are in opposite directions and of the same magnitude or strength. Where the snow frictional forces would decelerate, the tail wind would accelerate; the forces would balance, they would combine to be of no effect. This illustrates a deeper meaning of F = ma. Acceleration of a skier results from all the external forces acting; some may cause negative, some positive acceleration. The total force with contributions from all external forces is what matters. In our example, the snow frictional force and the pushing force of the wind are of equal strength and in opposite directions.
