Friction and Air Resistance - Essay Example

The narrowness of this region enables it to allow the penetration of anything that lies on the surface of the rock. The more the weight of the bighorn is running down to its hooves, the more the two digits make contact with the rock and tend to slide away from each other forming a v-shape. The v-shaped element formed enables the removal of slippery materials on the rocks and leaves it rough thus preventing the sheep from falling from the rocks. Air Resistance Pertaining to the air resistance, a cat jumping from a high floor tends to have lesser injuries than when it is falling from a lower height of the wall.

The reason behind this lies behind the notion of the rotation it makes with its body that increases the air resistance that acts against the forces of gravity pulling it to the ground. Thus, the more the air resistance, the lesser the injuries to the cat when it's rolling from a high wall (Walker, 2007). But when the cat is jumping from a lower height, it does not rotate its body, thus less air resistance is created (Walker, 2007)
