Ski Mountaineering
First, there are several Olympic sports played every four years. Ski mountaineering is one of them. In 2020 ski mountaineering was born. It started in Colorado. Ski mountaineering became an Olympic sport in 2022. The equipment needed for ski mountaineering is special skis that are skinny. They are special because there is special skin under the skis. The skin used to be made of animal skin. Now it is made from synthetic material that helps skiers from slipping. The rules are that athletes have to hike up the mountain. Then, take the skis off their back at the top and put the skis on their feet. Whoever comes down first wins. Ski mountaineering is very intense and also shows Newton's laws of motion.
The sport of ski mountaineering has many different forces. Newton's first law says, an object at rest stays at rest and an object in motion stays in motion, unless a force acts on it. These types of forces can be seen in the sport of ski mountaineering. Force is a pull and push. There are two kinds of forces: unbalanced and balanced. The forces working on the skis and person are gravity and friction. Balanced forces are still. An example of a balanced force is waiting for the race to start. When athletes are skiing this is an unbalanced force because they are moving and the skis are moving with them. Newton’s second law of motion states that the force on an object is made by the mass times the acceleration. Mass is anything that takes up space. The greater the mass the greater the force to move it. Examples of mass in ski mountaineering are the skis and athletes. Acceleration is a change of velocity. Examples of acceleration in ski mountaineering are the change in velocity of the skis and person. The force of the foot kicking into the skis impacts the acceleration of the skis by forcing the skis to move and change direction. The acceleration of the athlete in ski mountaineering is the player running and skiing. Athletes can predict the acceleration of objects by knowing how much force to apply when kicking their foot. Overall, Newton's second law of motion can be seen through ski mountaineering.
Newton third law states: for every action there is an equal and opposite reaction. An action is movement. Examples of movement are running, jumping and skiing. A reaction is an action that is responding to a motion. Examples of a reaction is hitting something and bouncing off. An example of this in ski mountaineering would be when someone shifts their body and turns on skis. If you turn enough you will stop. Another example is when athletes are running they go up the mountain. A final example is how the ski mountaineers do not slide backwards because of the special skins on their skis. The skis have special skin that help you from slipping backwards because they use friction to react against the slippery snow and gravity. Truly, physics can be seen throughout the world of ski mountaineering. The sport of ski mountaineering is fun and difficult. Newton's laws can be seen throughout every movement of ski mountaineering.
