# Topic: Circular motion

###### In the News (Mon 18 Mar 19)

 Circular Motion Under these conditions the particle is said to be undergoing uniform circular motion where "uniform" means the speed of the particle is constant. An acceleration of the sort we have been talking about, one that points toward the center of the circular motion of a particle, is called centripetal (center seeking) acceleration. In the Curved Path display you will see the path of a particle which is moving along the x axis at constant speed and subject to a force toward the x-axis proportional to the y displacement. www.mcasco.com /p1cmot.html   (1334 words)

 Physics 128 Lecture: Circular Motion Circular motion is a common type of motion. For the case of uniform circular motion an object moves in a circle at constant speed, though not at constant velocity of course. The centripetal force needed to maintain the circular motion of a object is inversely proportional to the radius of the circle. www.cord.edu /dept/physics/p128/lecture99_15.html   (1243 words)

 Circular Motion Principles for Satellites The fundamental principle to be understood concerning satellites is that a satellite is a projectile. Were it not for this force, the satellite in motion would continue in motion at the same speed and in the same direction. And in accord with Newton's second law of motion, the net force acting upon the satellite is directed in the same direction as the acceleration - towards the focus of the ellipse. www.glenbrook.k12.il.us /gbssci/phys/Class/circles/u6l4b.html   (1154 words)

 Physics 30: Applications of Kinematics and Dynamics - Uniform Circular Motion If an object is travelling in a circular path at constant speed its velocity is changing because, even though the magnitude of the velocity remains constant, the direction of the velocity is changing continuously. Illustrate the direction of the velocity vector, the centripetal acceleration vector, and the centripetal force vector for a moving object at a specific position on a circular path. Recognize that if an object were suddenly released from its circular path, it would tend to continue to move in the direction of the velocity vector, unless it was acted upon by some external force. www.sasked.gov.sk.ca /docs/physics/u5d3phy.html   (921 words)

 SparkNotes: Uniform Circular Motion: Uniform Circular Motion Since the particle is traveling in a circular path, the ratio of the change in velocity to velocity will be the same as the ratio of the change in position to position. The ball experiences uniform circular motion, and is accelerated by the tension in the string, which always points toward the axis of rotation. Thus the most important thing to remember regarding uniform circular motion is that it is merely a subset of the larger topic of dynamics. www.sparknotes.com /physics/dynamics/uniformcircularmotion/section1.html   (666 words)

 The Physics Classroom Uniform circular motion can be described as the motion of an object in a circle at a constant speed. An object undergoing uniform circular motion is moving with constant speed; nonetheless, it is accelerating due to its change in direction. The final motion characteristic for an object undergoing uniform circular motion is the net force. www.physicsclassroom.com /mmedia/circmot/ucm.html   (255 words)

 S.O.S. Mathematics CyberBoard :: View topic - please help me on the uniform circular motion.. A stone of mass 0.85kg is swung in a vertical circle at the end of a string with a fixed speed. Because the stone is in uniform circular motion, the only force acting on the stone is the centripetal force. That means the net force in both diagrams must be equal to the centripetal force (which points in the direction of the center of the circle). www.sosmath.com /CBB/viewtopic.php?t=10459&start=0&postdays=0&postorder=asc&highlight=   (649 words)

 S-Cool! - AS & A2 Level Physics Revision - Quicklearn Objects moving in circular motion clearly aren’t going in a straight line so the forces can’t be balanced. In linear or straight line motion, we measure speed by looking at how much distance is covered each second. If an object is moving with constant speed in circular motion, it is not going at constant velocity. www.s-cool.co.uk /topic_quicklearn.asp?loc=ql&topic_id=7&quicklearn_id=1&subject_id=2&ebt=153&ebn=&ebs=&ebl=&elc=13   (695 words)

 Circular Motion Although their motion is not perfectly circular, all the important characteristics of the motion can be described by mathematics developed for describing circular motion. This kind of motion is somewhat special in that the object of interest maintains a constant speed as it goes around the circle, i.e. When such a condition prevails, we say that the object is subject to a centripetal acceleration and that the object is undergoing uniform circular motion. dept.physics.upenn.edu /courses/gladney/mathphys/subsection4_1_3.html   (634 words)

 Knowledge   (Site not responding. Last check: 2007-11-05) Suppose that Fred says to you: "The fastest swimming stroke is the front crawl. One performs the front crawl by oscillating the legs at the hip, and moving the arms in an approximately circular motion". Here, Fred has propositional knowledge of swimming and how to perform the front crawl. knowledge.iqnaut.net   (1202 words)

 Including Sicence Of Cooking, Quick And Easy Menus, Cooking Tips If it's bubbling a lot at the sides of the pot, too, this is what's called a rolling boil. You can't stir down a rolling boil, which means if you take a wooden spoon and stir around the pot in a circular motion, the bubbles will keep coming up. Small bubbles can be stirred down - made to disappear - this way. www.greencooking.com   (1613 words)
