The Effects of Gravity     There are some people who stir up that when theyre outside, if they dont keep a good grip on the ground, theyll just go flinging off into space. They neednt really worry about this, because gravity generally keeps that way of thing from happening. The thing is, no peerless is really sure what causes gravity, provided the effects puzzle been studied by many physicists and astronomers. Three of the more obvious effects of gravity are things belittleing down, weight, and the the moon and planets staying in their orbits.     Things fall down. People have generally grown to accept that if one lets go of ones prized and valuable textbook when walking through a bollix throw, the book willinvariably end up in the puddle and therefore be stripped of all value and even legibility.Things fall down because there is a strong gravitational attraction mingled with things of greatmass, like the Earth, and things of little mass, like a book. The only worry with thisrelatively simple explanation is that no one really knows why its like that. What peoplehave figured out so farthermost is that gravity is a potency, and a force is anything that changes thestate of rest or motion of an object. In the absence of outside forces, the momentum of a ashes remains constant. This means that if there was no gravity, when one would relinquish ones allow in on the textbook, it would remain at rest in the air. If a force acts on a body, the body accelerates in the direction of the force. In the physical exercise of the force of gravity, small things like textbooks are pulled downward toward the center of the astronomic mass of the Earth, not up into space, even if some people regard that this might happen.                                         &nb sp         Torgerson 2     Isaac Newton was the first to conceive of weight as the gravitational attractionbetween a body and the Earth. The force that results from the gravitational attraction ofthe Earth on bodies at its surface is what we call weight. information has chosen to measure the mass of objects in units that are roughly same to the weight of those objects on Earth. For example, if a textbook weighs four pounds on Earth, it would have a mass of four pounds in an orbiting spaceship. The textbook would be "weightless" because it does not feel the gravitational attraction of the Earth, but, even in outside space, to push the
