PPT-Uniform Accelerated Motion

Kinematic Equations Measuring Techniques Assess Statements 211 215 217 2110 Due on Wednesday Oct 29 Uniform Accelerated Motion Acceleration The rate at which an objects velocity changes. . 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.. Sections 4.2 and 4.3. Updates & Reminders. The date and time of the final: Thursday, December 11 from 10 a.m. to 12 p.m. MLT 208. . There is no lab this week.. Test #1 will take place on Thursday, 9/18.. 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). 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 . 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 . Nature of science: . Observations: The ideas of motion are fundamental to many areas of physics, providing a link to the consideration of forces and their implication. The kinematic equations for uniform acceleration were developed through careful observations of the natural world.. 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. Projectile . Motion (Already Done!!!). Motion . on a Ramp. Circular Motion (coming your way in a few weeks). © 2015 Pearson Education, Inc.. Part 1 Motion on a Ramp. © 2015 Pearson Education, Inc.. 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. .
