Speed of a Satellite: A satellite revolves around the earth in a circular orbit. The necessary centripetal force is provided by the gravitational force of attraction. The centripetal force is given by the following formula: {eq}\beg...
"Mass" is a measure of how much matter an object has. "Weight" is a measure of the amount of force brought to bear on an object by gravitational attraction. Gravitational force changes based on location. For example, the gravitational force on the Moon is 0.165 of that here on Earth. W...
A dipolar molecule forms as a result of acharge separationbetween the negative chargedelectron cloudand the positive core, creating a permanentelectric dipole moment. Usually this charge separation originates in different attraction of the cores of different elements onto the negative chargedelectrons. D...
Why would things weigh only a quarter as much as they do at the surface of the earth if we took them 4,000 miles out into space? The reason is this: All objects have a natural attraction for all other objects; this is called gravitational attraction, but this power of attraction between...
