Paralympic Cross Country Skiing
Here are some parts about cross country skiing. It started in Ornskoldsviks and was introduced in 1976. You need skis or ski boots. You also need to cross the finish line. It’s a paralympic sport. Cross Country Skiing can also show Newton’s laws of motion.
Newton’s 1st Law shows rest and motion. Newton's 1st law of motion is an object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force. The objects at rest in my sport are the walls and sometimes the player. The object in motion in my sport is the player. The forces seen in my sport are drag force and muscular force.
Newton's 2nd law is seen in cross country skiing. Newton's 2nd law states that the acceleration of an object depends on the force applied and the mass of the object. Some forces are frictional force, muscular force, and drag force. The masses are the player, the skis, and the ski poles. The player might predict that they will go fast, slow, or stop. The player accelerates and stops using muscular force. They can change direction by using force to tilt the skis.
Newton’s 3rd law is seen in cross country skiing. Newton’s 3rd law states that every action has an equal and opposite reaction. Action is motion. An example of a reaction is an action after an action. An example of an action and reaction is the skier pushes off and the reaction is they start moving. Another example is they push backwards and the reaction is they move forwards. Those are Newton's three laws in cross country skiing.
