How does Newtons' first law affect skiing?

Answer 1

Newton's First Law Says: An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Assuming you mean downhill (or alpine) skiing. Gravity is that "unbalanced force" which makes us accelerate once we are on a slope. Friction from the air, and a small amount from the snow on your skis is fighting the force of gravity, but is not enough to balance it, and so you accelerate. Likewise, if you come to a flat spot on the snow, snow and air friction will gradually slow you down until you stop. Here, the level ground is providing a counter force to gravity (otherwise you would sink down into the ground!)

Answer 2

Newton's first law states that an object in motion will remain in motion unless acted upon by an external force. In skiing, this law explains why a skier continues moving down a slope at a constant speed unless they encounter friction or use their skis to change direction. It also illustrates the importance of balance and technique in controlling speed and direction while skiing.

Answer 3

Newton's laws of motion apply to every form of movement or motion. The trick is often in determining how the laws apply.

Think about what happens when someone is skiing. They are moving down the mountain, and aside from hitting a tree or the mountain ending, they will continue down the mountain. (1). A body in motion tends to stay in motion.

If the skier fails to miss a tree or another skier in his path, the force he exerts on the tree or other body will be the sum total of his velocity and mass. (2). The net force of a body is equal to the mass of that body times its acceleration.

The skier may succeed in missing the trees and other skiers by slaloming around them. As they do so they lean into turns. So for the action of turning, they lean into it to counteract the opposite action of falling over to the outside of the turn. (3). for every action there is an equal and opposite reaction.

Answer 4

Well, the first law deals with the fact the an object at rest stays at rest unless acted upon by an outside force, so perhaps as you're standing on the ice, ready to take off, that deals with the first law. You are at rest on the ice, but have potential energy. Once you take off, that gets into the second law.

Answer 5

you push DOWN with your feet and you move UP.
