Momentum
At the same time as the other peice of ice.
The bottom part of a fraction is the denominator.
friction helps us from falling over when doing simple tasks such as walking. the treds on the bottom of shoes have gaps between them giving greater surface area and friction can affect it more. this also occurs with skin, the finger prints and groves on skin all helps to hold things. hope this helps
That's where they get the friction
They go faster because they have a longer bottom which means they have a greater contact with the ground. More contact means more friction. This is what makes them go faster than smaller snowboards.

Collisions with the gas particles in the upper atmosphere.
If a liquid is poured into water and falls to the bottom the density must be greater than 1.
