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!)
Its a matter of being scientifically rigorous. You can not claim the 2nd law as a law unless you first establish the first law.
It isn't.
Actually, the first one is completely independent on the second one. But the second one doesn't make any sense without the first one.
It is sometimes referred to as the law of inertia.
By saying that the acceleration is zero.
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.

newtons first law: she will not move unless an outside force acts upon her, like her feet moving or her partner moving her!
In order to move the car, you will need to introduce an unbalanced force.
the law of inertia
yeah.
Law of inertia.
It affects it by newtons 1st law that an object at rest or motion will stay as such until acted upon by an outside force. -Metallica Man

Law of Inertia.
It isn't.
It is associated with the law of gravitational pull.
