PPT-Vertical Circular Motion

A demo httpwwwyoutubecomwatchvmrKLJjx9VT8 Motion in a Vertical Circle Consider the forces on a ball attached to a string as it moves in a vertical loop As with any object moving in a circle there is a net force acting towards the center of the circle. 2.4.1 Draw a vector diagram to illustrate that the acceleration of a particle moving with constant speed in a circle is directed towards the centre of the circle.. 2.4.2 Apply the expression for centripetal acceleration. . express angular displacement in radians. . understand and use the concept of angular velocity to solve problems. . recall and use . v = r. ω. to solve problems. . describe qualitatively motion in a curved path due to a perpendicular force, and understand the centripetal acceleration in the case of uniform motion in a circle. . 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. Equations:. Academic Vocabulary:. Centripetal force. Centripetal acceleration. Circular motion. Tangential velocity. Inverse square law. Gravitational constant. Universal gravitational force. Weightlessness. Theories of motion. Aristotle was a Greek philosopher who lived in the 4. th. century BC.. Aristotle explained the behaviour of a falling body by saying that its speed depended on how much earth element it contained. . © 2015 Pearson Education, Inc.. This lecture will help you understand:. Projectile Motion. Fast-Moving Projectiles – Satellites. Circular Satellite Orbits. Elliptical Orbits. Kepler. '. s Laws of Planetary Motion. What’s . Special About Perception?. Visual perception important for survival. . Likely optimized by evolution. at least more so than other cognitive abilities. Human visual perception outperforms all modern computer vision systems.. 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.. 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.. Physics. Coach Taylor. Broad Run High School 2010-2011. Objectives. Recognize that the vertical and horizontal motions of a projectile are independent.. Relate the height, time in the air, and initial vertical velocity of a projectile using its vertical motion, then determine the range.. Circular Motion. Objectives:. 1. Solve problems involving centripetal acceleration.. 2. Solve problems involving centripetal force.. 3. Explain how the apparent existence of an outward force in circular motion can be explained as inertia resisting the centripetal force.. 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. . Problems will be solvable using the equations of uniform acceleration. . .  . Projectile motion. This section is devoted to understanding the motion of projectiles. A projectile is an object upon which the only force acting is gravity.
