The path of least resistance down and given slope.

The straightest and steepest line down any slope.

The most direct route down the hill, often involuntarily taken by falling skiers.

(Jargon Rating= 3) The quickest route down the slope. Just follow gravity.

The steepest shortest and fastest line down any slope, the line of least resistance, which would be taken by, say, an un-steered sled down the slope.

The path the ball would take if left to gravity.

Ski. An imaginary line running straight downhill in the path in front of you. In skiing you usually cut back and forth across the fall line to control speed.

The most direct route down a ski slope.

The quickest path to the bottom of a run.

The line of gravity or the most direct route down a slope.

The most direct path down the mountain from any given point. It can be helpful to visualize the fall line as the path a ball would take if released from said point, or better, the path water would flow down. Experienced skiers and snowboarders tend to innately develop a feel for the fall line; however, even highly experienced climbers may not share this valuable ability

The path of least resistance down any given slope, the direction that gravity would pull you.

The line of fastest descent to the base of a wave (or mountain slope)

The path a ball would follow if rolled down a hill. In other words, the path of at least resistance down any given slope.

An imaginary line that combines the steepest pitch and most direct line, from top to bottom, of any slope.

The straightest way down a hill. If you let a ball roll down a hill it would go down the fall line.

A line parallel to that of gravity

The path directly down the hill.

The fastest route down a ski slope, but not necessarily the straightest.

a term used to describe the path of least resistance on a slope
