II Uniform Circular Motion A. Nomenclature 1. Speed – magnitude of an objects rate of motion (no direction‚ scalar quantity) 2. Velocity – speed and direction of an objects motion (vector‚ mag & direction) 3. If a car’s speed is constant but direction is changing‚ velocity is changing. 4. 2 ways to change velocity (change speed or change direction). 5. acceleration – change in speed over time (vector quantity) TWO types; a. Linear acceleration – speed

Perpetual Motion (of machines) is defined as “The motion of a machine that‚ once activated‚ would run forever unless subject to an external force”; is it possible? Let’s start off where it all began. Ever since the 8th century man has been attempting to build Perpetual Motion Machines‚ many were designs of a system of weights on a wooden wheel.[1] These work in a simple cycle starting with the weights on the left side‚ these weights hang close to the wheel resulting in a lower torque; but when the

Motion sickness Overview: The motion sickness is a deeper malaise - whose symptoms are nausea‚ vomiting‚ fatigue - due to non-uniform motion caused from traveling in a car‚ a ship‚ a train or a plane. Causes: You get motion sickness when one piece of your offset detecting framework (your internal ear camera.gif‚ eyes‚ and tactile nerves) detects that your body is moving‚ yet alternate parts don’t. Case in point‚ in the event that you are in the lodge of a moving ship‚ your internal ear may sense

Introduction The purpose of this section is to introduce the concepts of displacement‚ velocity‚ and acceleration. For the sake of simplicity‚ we shall restrict our attention to 1-dimensional motion. Displacement Consider a body moving in 1 dimension: e.g.‚ a train traveling down a straight railroad track‚ or a truck driving down an interstate in Kansas. Suppose that we have a team of observers who continually report the location of this body to us as time progresses. To be more exact‚ our observers

“PRINCIPLES OF MOTION ECONOMY” These 22 rules are principles of motion economy are profitably applied to many kinds of work. Although not all are applicable to every operation‚ they do form a basis or a code for improving the efficiency and reducing fatigue in manual work. USE OF THE HUMAN BODY 1. The two hands should begin as well as complete their motions at the same time. 2. The two hands should not be idle at the same time‚ except during rest periods. 3. Motions of the arms should be

the World in Motion Human beings are in constant search for sources that can provide them with adequate resources to meet their basic needs. The desire to get an adequate supply of resources has made people move from one location to another. However‚ people’s needs are complex and differ. This observation makes it difficult to have a specific factor to attribute human movement from one area to another. Bailyn asserts that the human world can best be described as the world in motion. In this type

Can slow motion replay improve jurors memory of evidence in a case? Caruso‚ Burns‚ and Converse (2016) examined the effect of video evidence on jury judgment of intentionality‚ the degree of which the harm caused was deliberate and premeditated‚ in criminal cases. Caruso et al. hypothesized that viewing a video in slow motion increases the perceived level of intent. After conducting four different studies‚ each with different variables‚ their results showed that slow motion footage perceives more

Projectile motion is a form of motion in which an object is thrown near the earth’s surface‚ causing it to move along a curved path under the action of gravity only. An example would be a football quarterback‚ when a quarterback throws the football in the air it goes upward and then travels back downward due to gravity. Gravity is the only force of significance that acts on the object which causes a downward acceleration. For example if Cam Newton throws a football over a long

The motion picture industry is a competitive‚ multi-billion dollar industry involving production crews‚ marketing crews‚ actors‚ directors‚ distribution companies‚ movie theaters‚ and movie rental companies. Four variables are commonly used to measure the success of a motion picture; these variables include the opening weekend gross sales‚ total gross sales‚ number of theaters showing the movie‚ and weeks in the top sixty of gross sales. Using a sample of 100 motion pictures from 2005 and numerical
