With Boyd, the changes involved first boosting his velocity, which also increased his spin rates, then altering the spin axis on his slider to eliminate its slight backspin, which allowed it to gain significantly more vertical depth and horizontal "sweeping" action about 5 inches of each more than his slider had in 2017, according to data at BrooksBaseball.net.
Launch conditions (spin, launch angle, trajectory, spin axis and strike point) all play a part to move a golf ball out down the fairway and the M5 and M6 provide a significant amount of fitting options to achieve the ideal conditions for any golfer.
The three orthogonal principal axes of rotation are a spin axis (along the length of the dancer's body) and two symmetric topple axes, with the origin at the ground.
told (https://www.smithsonianmag.com/smart-news/past-global-flood-shows-antarticas-ice-more-fragile-than-we-thought-180971075/) Smithsonian magazine that researchers speculated that warmer temperatures in the Northern Hemisphere at the time were caused by a slight change in the Earth's orbit and spin axis. This, in turn, caused climate changes around the world. 
Water ice can remain inside these craters because their floors are never exposed to direct sunlight, the consequence of a lunar spin axis that's nearly (within 1 1/2 [degrees]) perpendicular to the ecliptic plane.
The Georgia Tech study used simulations to analyze and identify the exoplanet's spin axis dynamics.
A new study from the Georgia Institute of Technology has used simulations to study the spin axis of the exoplanets.
I will determine the lithological and fluid characteristics and their possible related deposits, Water source triggering mechanisms, And will explain if it is by impact or spin axis / obliquity changes.
Moreover, the transmission law of the EATD azimuth tracking error in solar heliostats is analyzed, a dish concentrator system using a spin-elevation double-axis tracking device is proposed, and the transmission law of the tracking error from the spin axis to the dish concentrator was studied (in Section 4.4).
"Any major shift of planetary mass--on the surface or within the mantle--could cause a shift with respect to the spin axis, because a spinning body is most stable with its mass farthest from its spin axis."
As the rotor is spinning at [omega] radians per second therefore due to precession phenomenon the applied torque in one axis causes a motion in the axis which is perpendicular to itself and to the spin axis as well.
Matrix [I.sub.cg] is the inertia tensor of the SGCMGs about its spin axis of the gimbal, and Matrix [I.sub.ws] is the inertia tensor of the SGCMGs about its spin axis of the rotor.
