What Is Velocity in Physics

Velocity is defined as a vector measurement of the rate and direction of motion. Put simply, velocity is the speed at which something moves in a particular direction, such as the speed of a car traveling north on a major freeway, or the speed a rocket travels as it launches into space. The scalar (absolute value) magnitude of the velocity vector is the speed of the motion. In calculus terms, velocity is the first derivative of position with respect to time. You can calculate velocity by using a simple formula that uses rate, distance, and time. Velocity Formula The most common way to calculate the constant velocity of an object moving in a straight line is with the formula: r d / t where r is the rate, or speed (sometimes denoted as v, for velocity)d is the distance movedt is the time it takes to complete the movement Units of Velocity The SI (international) units for velocity are m/s (meters per second). But velocity may be expressed in any units of distance per time. Other units include miles per hour (mph), kilometers per hour (kph), and kilometers per second (km/s). Speed vs. Velocity and Acceleration Speed, velocity, and acceleration are all related to each other. Remember: Speed, according to its technical definition,  is a scalar quantity that indicates the rate of motion distance per time. Its units are length and time. Put another way, speed is a measure of  distance  traveled over a certain amount of time. Speed is often described simply as  the distance traveled per unit of time. It is how fast an object is moving.   Velocity, by definition,  is a vector quantity that indicates distance per time and direction. Like speed, its units are length and time, but direction is also involved in the equation. Velocity measures displacement over time, as opposed to distance. Acceleration  is defined in technical terms as a vector quantity that indicates the rate of change of velocity. It has dimensions of length and time. Study.com puts it in simpler terms: Acceleration is often called speeding up, though it would more accurately be referred to as velocitying up. The everyday experience of acceleration is in a vehicle. You step on the accelerator and the car speeds up as increasing force is applied to the drive train by the engine. Why Velocity Matters Velocity measures motion starting in one place and heading toward another place. In other words, you use measures of velocity to determine how quickly you (or anything in motion) will arrive at a destination from a given location. Measures of velocity allow you to (among other things) create timetables for travel. For example, if a train leaves Penn Station in New York at 2 p.m. and you know the velocity at which the train is moving north, you can predict when it will arrive at South Station in Boston. Sample Velocity Problem To understand velocity, it can be helpful to peruse a sample problem. For example,  a physics student drops an egg off an extremely tall building. What is the eggs velocity after 2.60 seconds? The hardest part about solving for velocity in a physics problem is selecting the right equation. In this case, two equations may be used to solve the problem. Use the equation: d vI*t 0.5*a*t2 where d is distance, vI is initial velocity, t is time, and a is acceleration (due to gravity, in this case). So, you would have: d (0 m/s)*(2.60 s) 0.5*(-9.8 m/s2)(2.60 s)2d -33.1 m (negative sign indicates direction downward) Next, you can plug in this distance value to solve for velocity using the equation: vf vi a*t where vf is final velocity, vi is initial velocity, a is acceleration, and t is time. Since the egg was dropped and not thrown, the initial velocity is 0. vf 0 (-9.8 m/s2)(2.60 s)vf -25.5 m/s So, the velocity of the egg after 2.60 seconds is 25.5 meters per second. Although its common to report velocity as a simple value, remember its a vector and has direction as well as magnitude. Usually, moving upward is indicated with a positive sign, and down carries a negative sign.

Jessica Toelle Beth Orozco ENG102 29 February 2016 The Glass Menagerie by Tennessee Williams Tennessee Williams, born Thomas Lanier Williams, wrote The Glass Menagerie, a play which premiered in Chicago in 1944.

The Silk Road Essay Research Paper The free essay sample

The Silk Road Essay, Research Paper The Silk Road is the most well-known trading path of ancient Chinese civilisation. Trade in silk grew under the Han Dynasty in the first and 2nd centuries. Originally, the Chinese trade silk internally, within the imperium. Caravans from the imperium # 8217 ; s inside would transport silk to the western borders of the part. Often little Central Asian folk would assail these trains trusting to capture the bargainers # 8217 ; valuable trade goods. As a consequence, the Han Dynasty extended its military defences further into Central Asia from 135 to 90 BC in order to protect these trains. Chan Ch # 8217 ; ien, the first known Chinese traveller to do contact with the Central Asian folk, subsequently came up with the thought to spread out the silk trade to include these lesser folks and hence forge confederations with these Central Asian nomads. Because of this thought, the Silk Road was born. Northwestern Indians who lived near the Ganges River played outstanding functions as jobbers in the China-Mediterranean silk trade because every bit early as the 3rd century AD, they understood that silk was a moneymaking merchandise of the Chinese Empire. We will write a custom essay sample on The Silk Road Essay Research Paper The or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The trading relationship between the Chinese and the Indians grew stronger with increased Han enlargement into Central Asia. The Chinese would merchandise their silk with the Indians for cherished rocks and metals such as jade, gold, and Ag, and the India ns would merchandise the silk with the Roman Empire. Silk proved to be an expensive import for the Roman Empire since its trade across Indian and Cardinal Asia was to a great extent controlled by the Parthian Empire. While the Chinese silk trade played a minor function in the Chinese economic system, it did increase the figure of foreign merchandisers present in China under the Han Dynasty, exposing both the Chinese and visitants to their state to different civilizations and faiths. In fact, Buddhism spread from India to China because of trade along the Silk Route, similar to the manner Islam spread along paths in mediaeval West Africa. . By 760 AD, during the T # 8217 ; ang Dynasty, trade along the Silk Road had declined. It revived enormously under the Sung Dynasty in the eleventh and 12th centuries when China became mostly dependent on its silk trade. In add-on, trade to Central and Western Asia every bit good as Europe recovered for a period of clip from 1276-1368 under the Yuan Dynasty when the Mongols controlled China. The Chinese traded silk for medical specialties, aromas, and slaves in add-on to cherished rocks. As overland trade became progressively unsafe, and overseas trade became more popular, trade along the Silk Road declined. While the Chinese did keep a silk-fur trade with the Russians North of the original Silk Route, by the terminal of the 14th century, trade and travel along the route had decreased.
