    Gravity

    Gravity is really an unknown force. We can define it as a field of influence, and that it effects the entire existence of the universe. Some people think that gravity consists of particles called gravitons, which travel at the speed of light. The only thing we do know is how gravity operates in different parts of our universe. Without gravity, there would be no space and time. There is a legend that says that Galileo once dropped two objects off the Leaning Tower of Pisa to show that the heavier

    The Effects of Gravity There are some people who worry that when they're outside, if they don't keep a good grip on the ground, they'll just go flinging off into space. They needn't really worry about this, because gravity generally keeps that sort of thing from happening. The thing is, no one is really sure what causes gravity, but the effects have been studied by many physicists and astronomers. Three of the more obvious effects of gravity are things falling down, weight, and the the moon

    Gravity Experiment My physics coursework is an experiment with gravity. The experiment is done by creating a parachute with a plastic bag. The parachute has a given area and is usually square shaped. This means that the area is easily calculated. There are lengths of string attached to the chute which hold a ball of play dough at the bottom. [IMAGE] To do the experiment we have a choice of either keeping the mass of the play dough the same and keep changing the area of the chute, or

    SCM-Variation Gravity-Centrifugal-Power-Motor Objectives At chapter Swing-Circuit-Motor (SCM) above, a design was worked out corresponding to build-up of a loop-swing. There, two axis were demanded (system- and excenter-axis) and two ´wheels´ did turn within each other. So this will be a rather difficult technical construction. By this chapter now shall be examined, how effect of building-up mechancal oscillations could be realized easier. So only one axis should be neccessary, nevertheless masses

    Using a Pendulum to Find Gravity Aim: To find the gravity by finding the period of the oscillations of a pendulum and plotting a graph. Hypothesis and Prediction: - the gravity from the graph is going to equal the gravity from the formula. Variables: The independent variable is the length of the string The Dependent variable is the period of one oscillation Controlled variables are: - mass of the pendulum Equipment: -Brass Ball -string -boss and clamp -stopwatch

    Finding Acceleration Due to Gravity Using Ball Drop Method Aim: To calculate the acceleration due to gravity by dropping a ball from a certain distance and recording the time Hypothesis: it is expected that the gravity should be within the same range for each trial Variables: The independent variable = the distance The dependent variable = the time Controlled variables are: - the mass of the steel ball - the position of the trip plate -the length of the plumb line

    analyze two reviews on the movie Gravity, a film about two astronauts’ fight for survival after space debris destroys the shuttle and communications with Mission Control are lost. The first review is from The New York Times and was written by A.O. Scott. The second article is from The Guardian and was written by Peter Bradshaw. After analyzing both articles, I have found A.O. Scott’s article to have better overall rhetorical strategies. A.O. Scott argues that Gravity is a terrifying yet marvelous story

    full move back and forth. The equation used to solve for the period mathematically is T = 2p (square root of L/g), where L is the length of the pendulum, and g is gravity. There are a few things that can change the period of a pendulum. As length increases and as the force of gravity increases so will the period. Likewise, when both gravity and length of the chains decrease, the period does also. My reference Mark Nethercott says that if there are no outside influences, the period stays constant at

    resistance. This can easily be observed because it takes an extended time for the pendulum to stop swinging, so only a small amount of energy is lost on each swing. Gravity The pendulum is motivated by the force of gravity acting on it. The more gravity the shorter time it will take for a complete swing. The less gravity the longer it would take for a complete swing Size of swing The size of the swing does not have large effect on the time. Mass The mass of the pendulum does

    an attempt by humans to model the four fundamental forces of physics as vibrations of tiny supersymmetric strings. Superstring theory seems the most likely to lead to theories of quantum gravity, an attempt to explain gravity’s relatively weak force when compared to the other forces of physics (“Quantum gravity”, nd). Superstring theory is also "supersymmetric string theory." It is referred to as this because unlike bosonic string theory, the original form of string theory (Bosonic string theory
