PPT-More Centripetal Force Problems

We have already seen the forces acting on a mass moving in a horizontal circle now lets see how this differs from a mass moving in a vertical circle Draw the forces acting on a mass on a string being spun in a vertical circle at the . and . Centripetal Force. Acceleration. Speeding up. Slowing down. Changing direction. . Think of spinning an object on the end of a string. How would you describe it to someone?. The easiest thing to say is that it moves in the shape of a circle.. 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. Presenter: . Hallie. . Hundemer. -Booth. Student Achievement Partners. ELA/Literacy: 3 shifts. Building knowledge . through . content-rich nonfiction. . Reading, writing, and speaking grounded in . Equations:. Academic Vocabulary:. Centripetal force. Centripetal acceleration. Circular motion. Tangential velocity. Inverse square law. Gravitational constant. Universal gravitational force. Weightlessness. In circular motion with a constant centripetal force.. Applying Newton’s 2. nd. Law. In this case the only force on the body is the force of gravity and the acceleration of the body is centripetal.. © 2015 Pearson Education, Inc.. This lecture will help you understand:. Circular Motion . Rotational Inertia. Torque. Center of Mass and Center of Gravity. Centripetal Force. Centrifugal Force. Rotating Reference Frames. Magnetic Forces. Objectives: . FLASHBACK. FLASHBACK: Sketch a stress-strain graph for a malleable materials and label a) the limit of proportionality b) the elastic limit c) the ultimate tensile strength d) the breaking point. Uniform circular motion and Universal Gravitation. Centripetal Acceleration & Force. Centripetal Acceleration & Force. This unit we will investigate the special case of kinematics and dynamics of objects in . Calculate angular speed in radians per second.. Calculate linear speed from angular speed and vice-versa.. Describe and calculate centripetal forces and accelerations. .. Motion . in Circles. We say an object . in Circular Motion (cont.). © 2015 Pearson Education, Inc.. Centrifugal Force?. If you are a passenger in a car that turns a corner quickly, it is the force of the car door, pushing inward toward the center of the curve, that causes you to turn the corner.. 002. Lecture . #12. Wednesday. ,. Feb. 27, 2013. Dr. . Jae. hoon . Yu. Uniform Circular Motion. Centripetal Acceleration. Newton. ’. s . Law & Uniform Circular Motion . Example. Unbanked . and Banked . 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. They contain important ideas and questions from your reading. . Due to time constraints, I was probably not able to show all the slides during class. . T. hey are all posted here for completeness..
