An object in motion stays in motion with the same velocity unless acted on by an unbalance force. That is newtons 1st law. Skiing demonstrates this because you are staying in motion by resisting the force of gravity and friction, so you are the inbalance force. An ubalanced for is a force when two object pushed against each other and one wins. So there is an unbalanced for. So when you skiing your that ubalanced force which is resisting gravity and friction.

∙ 9y agoIts a matter of being scientifically rigorous. You can not claim the 2nd law as a law unless you first establish the first law.
the law of inertia
yeah.
Law of inertia.
Newton's second law deals with mass and force as it relates to acceleration. Acceleration down the hill is the main part of skiing, which skiers can affect by changing their mass or the force they use to push themselves down the hill.

Law of Inertia.
It isn't.
Yes, Newton's first law of motion applies to bicycling. It states that an object in motion will stay in motion unless acted upon by an external force. When you're riding a bike, you will keep moving forward at a constant speed unless you apply the brakes or encounter obstacles that cause you to stop.
It is associated with the law of gravitational pull.
Newton's First Law of Motion, also known as the Law of Inertia, states that an object at rest stays at rest and an object in motion continues in motion with the same speed and in the same direction unless acted upon by an external force.
Actually, the first one is completely independent on the second one. But the second one doesn't make any sense without the first one.
