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.
We have already met gravitational fields, where the gravitational field strength of a planet multiplied by an objects mass gives us the weight of that object, and that the gravitational field strength, of Earth is equal to the acceleration of free fall at its surface, .he gravitational field strength at a point is the force per unit mass exerted on a mass placed at that point. This means that the gravitational field strength, is equal to the force experienced by a mass of 1kg in that gravitational field.
