Term 3 Uniform Circular Motion When a body moves in a circular path with a constant speed‚ it is said to undergo uniform circular motion. Although the speed is constant‚ velocity is continually changing‚ since it is constantly changing its direction of motion. Centripetal V V ac ac Acceleration is directed towards the centre of the circle and is therefore called “centripetal acceleration.” ac =v^2r ac =v^2r If T is the time taken for one revolution then: V = 2πrT ac =v^2r

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

Moses Ochieng Newton’s Second Law of Motion Objective As you are probably aware from everyday experience‚ heavier objects require a greater force to move around than lighter ones. Isaac Newton quantified observations like this one into what is probably the most useful expression in all physics: F = M a‚ otherwise known as Newton’s Law of Motion. Here‚ F is the net external force acting on mass M‚ and a is the resulting acceleration. The primary objective for this lab is to test the conjecture

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

“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

He went to Cambridge University in 1661 and became interested in math‚ physics‚ and astronomy. Newton received a bachelors and masters degree. (online) What he is most famous for is developing his three laws of motion. The first law is that an object in motion tends to stay in motion with the same speed going in the same direction unless acted upon by an unbalanced force. An object at rest tends to stay at rest unless acted on by an unbalanced force. His second law states that acceleration is

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

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
