Centripetal Force Space Shuttle

Apart from any acceleration that might occur in the direction of the path, the lower panel of the image above indicates the forces on the ball. There are two forces; one is the force of gravity vertically downward through the center of mass of the ball mg, where m is the mass of the ball and g is the gravitational acceleration; the second is the upward normal force exerted by the road at a right angle to the road surface man. The centripetal force demanded by the curved motion is also shown above. This centripetal force is not a third force applied to the ball, but rather must be provided by the net force on the ball resulting from vector addition of the normal force and the force of gravity. The resultant or net force on the ball found by vector addition of the normal force exerted by the road and vertical force due to gravity must equal the centripetal force dictated by the need to travel a circular path. The curved motion is maintained so long as this net force provides the centripetal force requisite to the motion.



Bringing Birth Chart Astrology Down To Earth. This the first of a series of articles in which I try to bring Astrology down to Earth, by explaining what each planet represents in us at a basic level. This article explains the Moon, which is one of the Ego planets, Sun and Saturn being the other two, understanding each in turn and learning to see them as sub-personalities that need to work together to make you feel secure, worthwhile and complete. An awareness of these different energies will help in the understanding of your inner core self which is needed before the process of integration can successfully occur. "Makemake is in the class of rare Pluto-like objects, so finding a companion is important. The discovery of the moon has given us an opportunity to study Makemake in far greater detail than we ever would have been able to without the companion," Dr. Parker continued to explain. Moon in Earth (Taurus, Virgo or Capricorn) will be in their element when they are making money, adding to their resources or making their home cosy, comfortable or beautiful. They cannot just wish or believe, they need to have and to hold the tangible or to make progress in order to feel secure. They react in a grounded, steady and matter- of-fact manner, which can turn into stubbornness and a reluctance to change or let go. They are very much at home when working or being productive in their practical way.
