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.
Electric Field. Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge. Click on any of the examples above for more detail. Lorentz force law
