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.
Each planets revolve around a different axis of rotation. The axial tilt or obliquity is the angle between the axis of rotation of a planet and perpendicular to its orbital plane. The planets glide majestically on an orbit around the Sun, leaving perceive no trace of the gravitational constraints that lead.his rotation axis is never perpendicular to the orbital plane of the planet, but inclined at an angle varies according to the planets (see picture against). In the case of Earth, this angle was 1 January 2013 to 23 Â° 26'15, 32 .
