Then, the process of becoming pregnant takes several days -- the fertilized egg (now called a blastocyst) has only just begun its long journey. Once the egg is fertilized, it now has to travel all the way up into the uterus for implantation to take place. As the blastocyst makes this journey, it will continue to grow in size. At the same time, its cells will continue to divide and reproduce.
gravitational field - a field of force surrounding a body of finite mass. field of force, force field, field - the space around a radiating body within which its electromagnetic oscillations can exert force on another similar body not in contact with it.
Gravity is the force of attraction between all masses. Although gravity is said to be exerted by everything that has a mass, only those objects with very large masses actually affect anything near them. A gravitational field is the area around the body that is exerting the gravitational pull.It can be defined as the gravitational force felt by a unit's mass placed at a point in space. Gravity has three very important effects. First, it makes all things accelerate towards it.ravity is the force of attraction between all masses.
