PPT-Uniform Motion and Graphing

Uniform motion objects travel equal displacements in equal amounts of time Ex Think of Ice skating when you push off the boards you would glide across the ice and then eventually stop because of the friction between the ice and your skate blades But if it was . . An appeal by IUA and UNESCO: . “… the citizens of the world rediscover their place in the Universe through the day- and night-time sky observation, and thereby engage a personal sense of wonder and discovery… . 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.. Kinematics Terminology. Scalar vs. Vector. Scalar: . quantities that have only a size, but no direction. i. e. : . distance, speed. Vector: . quantities that have a size and direction. ie. : . displacement, velocity. Equations of Motion for Constant Resultant Force. Also called ….. because………. …acceleration and resultant force are directly proportional. . s. uvat. equations. Also called ….. (unhelpfully). 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.. Clarification: Vector symbol. Technically the variable for speed is . v. and the variable for velocity is . v .. In homework and on tests you do not need to be so formal. . You can leave off the arrow over the . 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 . Uniform Motion and Uniform Accelerated Motion. Read pages 27-36. Average and Instantaneous Velocity. Average Velocity .  rate of change in position. . - Found by considering total displacement (change in position) in a time interval). You can see it on a. . . position time . graph OR. a . velocity time . graph. POSITION v TIME. Velocity is seen by the . slope. Graphing motion. position-time. Section 1 on graph represents biker going forward. . Slope = rise ÷ run. Speed = distance ÷ time. Therefore: . Distance = rise. Time = run. The slope of a distance-time graph is speed. Y2 – Y1. ------------. X2 – X1. Speedy Gonzales!. 160. 140. . Motion. Speed & Velocity. Acceleration. Newton’s First Law. Newton’s First Law of Motion. An object at rest will remain at rest and an object in motion will continue moving at a constant velocity unless acted upon by a net force.. Day 1. Warm – Up:. Choose a new seat with . different neighbors.. Get with a partner and discuss: What is motion? How do you know if something is moving?. Write your answers down and be ready for a class discussion.. 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. . Scientist interpret tables, graphs, and diagrams to locate data, examine relationships in the data, and extend those relationships beyond the data.. Reading graphs can be like reading a foreign language though. It come easy to some and very difficult to others..
