Ski Base Materials

 

The materials that are used on the bottom of a ski bear great importance to its performance. The ski must have a base that when waxed will have a minimal coeffecient of kinetic friction, as to attain top speeds.

Theta

Normal force

Mg sin(theta)

Mg cos(theta)

F_f

Mg sin( theta) - Frictional force = ma_x


Thus when the frictional force is less, ma_x will be bigger, giving the object a greater velocity.
