inextensible 1 stop-watch / 1 triple beam balance / scissors / Sketching of the set-up Theory Centripetal force F is the net force causing the centripetal acceleration of an object performing uniform circular motion. Its magnitude is given by the equation: F = mrω2 When an object is whirled in horizontal circular motion in mid-air with a piece of string (as shown in figure 1 above)‚ the centripetal force on the object is provided by the horizontal component of tension in the string: 2 =>2 (since r = L)

Uniform Circular Motion PES 115 Report Objective The purpose of this experiment is to determine the relationships between radiuses‚ mass‚ velocity and centripetal force of a spinning body. We used logger pro to accurately measure the orbital period of the spinning mass and used these measurements to determine the interrelated interactions of the specified properties and viewed the results graphically. Data and Calculations The black markings on the string are about 10 cm apart in length‚ measured

or rocket‚ appear to be deflected from their trajectory‚ meaning they don’t reach their intended location straight ahead of them. In fact it is our frame of reference‚ the Earth‚ which is changing. Our frame of reference changes due to our uniform circular motion around the Earth. As the Earth is not a perfect circle (elliptical)‚ the closer to the equator you are‚ the further away you are from the Earth’s centre and the less force of gravity you experience. The Earth’s radius is 6378 km. As a result

Against School Uniforms School Uniforms I understand that many schools around the nation wear uniforms for a good reason. Such as if kids could not purchase enough clothes normally. I completely respect that and the schools which choose to do so. However‚ I do strongly believe that children have the right to wear whatever they want to school as long as it is appropriate. I myself have never attended a school in which uniforms are required. But I do know kids who have and a lot of them say they

A uniform is a type of clothing worn by members of an organization while participating in that organization ’s activity. Modern uniforms are most often worn by armed forces and paramilitary organizations such as police‚ emergency services‚ security guards‚ in some workplaces and schools and by inmates in prisons. In some countries‚ some other officials also wear uniforms in their duties; such is the case of the Commissioned Corps of the United States Public Health Service or the French prefects.

of a process called motion capture. Motion capture has been around since the late 1970s‚ where it was then called rotoscoping and was used by Walt Disney in the film Snow White (Sturman). To begin with‚ the term “motion capture” actually has many different names‚ such as mocap‚ performance animation‚ performance capture‚ virtual theater‚ digital puppetry‚ real-time animation‚ and the favorite among traditional key frame animators is “The Devil’s Rotoscope” (Furniss). Motion capture‚ in its most
