PPT-Uniform Circular Motion October 2014

Circular Motion A is towards the center V is tangential to the motion Speed is constant V changes A force directed towards the center is what causes the acceleration eg gravity . Chapter 5. Learning Objectives- . Circular motion and rotation . Uniform circular motion. Students should understand the uniform circular motion of a particle, so they can:. Relate the radius of the circle and the speed or rate of revolution of the particle to the magnitude of the centripetal acceleration.. Circular motion. We will be looking at a special case of kinematics and dynamics of objects in uniform circular motion (constant speed). Cars on a circular track (or on a curved road). Roller coasters in loop. A bunch of stuff you’ll see on the midterm exam. Question 1. Give the formula for speed in a circle of radius r. Give the formula for centripetal acceleration. Give the formula for centripetal force. 5.1 . Uniform Circular Motion. DEFINITION OF UNIFORM CIRCULAR MOTION. Uniform circular motion is the motion of an object . traveling at a constant speed on a circular path.. 5.1 . Uniform Circular Motion. Circular Motion Lab Results. Part 1: Radius’ effect on velocity. Mass, centripetal force kept constant. Part 2: Mass’ effect on velocity. Radius, centripetal force kept constant. Part 3: Force’s effect on velocity. Supported by . UBC. Teaching and Learning Enhancement Fund . 2012-2015. Department of . Curriculum and Pedagogy. FACULTY OF EDUCATION. Question Title. Question Title. Circular Motion. http://. nwsphysics99.blogspot.ca. Centripetal acceleration. Problem solving with . Newton’s 2nd Law . for . circular motion. Lecture 8: Circular motion. Effect of force components . Components of force parallel and perpendicular to velocity have different effects.. Carry the motion over a distance. And. Change the type of motion. Transmission of motion. A group of simple machines can work together to make a . system. .. A system can transmit or carry the motion from one object to another.. 5-1 Uniform Circular Motion. Uniform Circular Motion. : The motion of an object traveling at a constant (uniform) speed on a circular path. 5-1 Uniform Circular Motion. Since we are dealing with object moving in a circle, it is convenient to talk about the . Can you change your velocity while not changing your speed?. v. F. Consider the above situation.. According to Newton . S. econd law, what must the object be doing?. It is accelerating so the velocity must be changing.. Uniform Circular motion. For an object moving on a circle at constant speed. The . speed is constant. , but the . direction is not. Acceleration is a change in velocity, but speed is constant. The change in velocity is only in its direction. Doug . Backman. Module 3. OMB Circular A-110. Uniform Administrative Requirements. Doug Backman. Exploring Research Administration…for CONCEPT to COMMERCIALIZATION. AGENDA. Authority & Definitions. Uniform circular motion. What does the word “. uniform. ” mean here?. . constant radius. and . constant speed. . Velocity vector is tangent to the path at each instant, so direction of velocity vector changes all the time as the object moves in circle. .
