Formal motion and time study‚ however‚ goes somewhat beyond the concept of work simplification and streamlining of processes. One author lists four distinct parts to the process‚ namely‚ (1)finding the most economical way of doing the job‚ (2) standardizing the methods‚ materials‚ and equipment‚ (3) determining accurately the time re- quired by a qualified person working at a normal pace to do the task‚ and (4) assisting in training the worker in the new method. The differ- ent parts may be considered

Curvilinear Motion Projectile Motion When the player hits the “Sepak”‚ the motion of the “Sepak” is called projectile motion. The “Sepak” itself is called projectile. The “Sepak” will follow a parabolic path called trajectory especially if air resistance is negligible. Two coordinates are usually used to describe projectile motion: horizontal and vertical axes. The horizontal distance traveled by the projectile is called the range. While the vertical distance‚ that is‚ the distance from where

Johannes Althusius (about 1563 – August 12‚ 1638) [1] was a German jurist and Calvinist political philosopher. He is best known for his 1603 work‚ "Politica Methodice Digesta‚ Atque Exemplis Sacris et Profanis Illustrata"; revised editions were published in 1610 and 1614. The ideas expressed therein have led many to consider him one of the first true federalists as the greatest intellectual thinker in the early development of federalism in the 16th and 17th centuries and the construction of subsidiarity

Lebanese American University Classical Physics 3 . Projectile Motion Objectives: Students will measure the maximum height H and the range R of a projectile motion. They will study the effect of the shooting angle on H and R. Material used: 4 rulers‚ track‚ metallic ball‚ landing track‚ A4 white paper‚ red carbon paper‚ timer + supply‚ gun + protractor. Theory: A projectile is an object upon which the only force acting is gravity. There are a variety of examples of projectiles: an object

Experiment 4 Projectile Motion Introduction We examined projectile motion by observing a ball rolling down then leaving the ramp‚ thus becoming a projectile with a horizontal initial velocity. We measured the horizontal initial velocity using the photogate and computer. We measured the horizontal and vertical distances that the projectile traveled from the end of the ramp to when it hit the floor my using a meter stick to measure Experimental Set-Up In our experiment‚ we used the following:

Johannes Gensfleisch zur Laden zum Gutenberg‚ more commonly known as Johannes Gutenberg‚ was a man of the Renaissance. Johannes was born in approximately 1400 in Mainz‚ Germany into an upper-class family. His father was named Friele Gensfleisch zur Laden. According to some‚ he was a goldsmith for the bishop at Mainz‚ but most believe he was involved in the cloth trade. Johannes did many things to help the Renaissance times‚ and also to help us today. He invented the Printing Press and was also a

Assessment Task #1: Part A Open ended investigation By Rex Whiticker Projectile Motion Abstract: The Project motion of a catapult being fired is varied by a range of factors that affect the path of the projectile. In this experiment‚ the angle of trajectory‚ mass of the projectile and change in initial velocity of the launch‚ were all factors considered in the end result to investigate the properties of projectile motion. The purpose of the experiment was to conduct a first-hand investigation to design

But Niels Bohr looked into this and found out that electrons move in paths around the nucleus. Surprisingly these electron can move from one path to another. They can also jump to a path that is a level above. Bohr created a model called the planetary model. This model shows how the electron move in different energy levels. Enrico Fermi -- 1940 Enrico Fermi was the very first person to create a nuclear reactor‚ a device used to control nuclear chain reactions. It is mostly used today to

Projectile motion is the act of projecting an object into the air at an angle when a curved path is an object follows when thrown or propelled near the surface of the earth.For example: a thrown football‚ an object dropped from an airplane‚ or a bullet shot from a gun.Projectile motion may only be used to solve mechanics problems if the acceleration is constant.The path followed by a projectile is
