Acommon visual behavior is the âhead jerk.â This motion is generally observedwhen an individual otter approaches a raft of sea otters. The approaching otternoses and sniffs the other otters while jerking its head from side to side.
Axis tilt is the vertical angle at which the ball rotates. Axis tilt is what is commonly known as spin. Axis tilt is determined by the position of the thumb during the release. If the hand turns too early, the thumb exits on top of the ball. Bowlers with a high degree of axis tilt will be able to see the top of their hand during the release and follow through.
It is inclined 66.5 degrees from Earth's orbital plane, which means that it is tilted 23.5 degrees from a vertical 90 degrees. Generally, an axis is any imaginary or physical line that prescribes an object's movement. A taut string that goes through the center of a spinning ball would be an example of a physical axis.
