Gravity's Grasp – Essay Example
The paper "Gravity's Grasp" is a worthy example of an essay on formal science and physical science. Gravity depends on the masses of two interacting bodies as well as on the distance between these two bodies. As such, the gravitational force between two bodies is entirely proportional to the masses of these bodies and to the distance separating them. A shorter distance means that the gravitational pull will be stronger. On the other hand, a long distance between the two objects means that the gravitational pull will be weaker. A large mass creates a bigger gravitational pull than a smaller mass (Schultz, 2003). These gravitational constructs elucidate the manner in which gravity operates within two apparent objects. For instance, it is this same principle that holds the planets in their orbits around the sun in the solar system. Consequently, if one of the two bodies locked in a gravitational balancer were to escape the orbit, a number of factors would have to come into play to determine the escape velocity. The reason behind this is the fact that the necessary escape velocity has to be fast enough to pull one of these objects from the orbit against the pull of gravity. According to Schultz (2003), the two major factors that affect the necessary escape velocity are is the mass of the planet or sun in kilograms (kg), and the separation distance between the center of the mass of the sun or the planet and the center of the object. As mentioned above, a larger mass will make the separation faster while a smaller mass will make the escape velocity slower. A wider separation distance reduces the escape velocity and vice versa.
