Rocket Propulsion
When I first thought of rocket propulsion it sounded very complex and hard to understand. I could not image that rockets could move in space where there is no friction. This concept is easy to understand now that I know escape velocity and conservation of momentum. These elements are easy to understand once the basics are learned. In order to send a rocket into outer space we must escape our gravitational pull. Earth’s gravity gets smaller and smaller as you get further from the center of the earth. Therefore, when an object that has been thrown up into the air stops acceding and starts descending, it is because of the gravitational field of the earth. Lets say you throw an object up into the air and it does not return to the earth’s surface. You have given the object escape velocity which is defined, as the minimum amount of velocity an object must have in order to escape the gravitationa
