a particular anti-atom will escape when its axial kinetic energy exceeds the combined gravitational and magnetic potential at the peak axial field position of one of the mirror coils. Thus, one could balance the effect of gravity on matter by imposing a field difference (BG ...
The relationship between the form and structure of plants and their gravitational environment is one of the most important teaching subjects of biological education. However, the teaching materials for the gravity effect have so long been concerned only with gravitropism, i.e. the short-time response...

The more massive an object is, the less effect a given force will have.") Driving Question for the Unit: What is a force and how does it impact the motion of objects on Earth? Investigation Questions for the week of lessons: (based on driving question, friction, and gravity) ...
aThe effect of such a weight movement on the righting moment at this angle is to move the ship's center of gravity in a direction parallel to the movement of the center of gravity of the weight. 这样重量运动的作用在正确的片刻在这个角度是移动船的重心在方向平行与重心的运动重量的。[translate...
According to Einstein's theory of General Relativity when a ray of light passes close to a very massive object, the gravity of the object attracts the photons and deviates them from their intial path. This phenomenon, known as gravitational lensing, is comparable to that produced by lenses on...
The purpose of the study was to examine the effect of body orientation with respect to gravity on infant′s reaching quantity and quality. Two groups, 12- to 19-week-old and 20- to 27-week-old infants, were seated in three positions: vertical (90° from horizontal), recline (60°), ...
