College Physics I. Fall 2012. S. A. Yost. Chapter 11 . Simple Harmonic Motion. Announcements. Problem set 10B is due Thursday. . Read . sections 1 – 4 and 7 – 9 . if you haven’t. Topics. : simple harmonic motion, intro to waves.. Typically, harmonic motion decreases in amplitude with time….this realistic model describes damped harmonic motion.. The damping effect is a result of friction and internal resistance of the system to further motion.. Prepared by;. Dr J P SINGH. Dept of Physics. P.G.G.C-11, Chandigarh. Email: drrajeshsharma@in.com. Periodic Motion. : any motion of system which repeats itself at regular, equal intervals of time.. Oscillatory or vibratory motion:. Simple Harmonic . Motion (SHM). periodic. motion about an . equilibrium point . where the restoring force is proportional to the distance from equilibrium. For oscillation to be . SHM, . the forces must always be directed to the . Chapter 15. Copyright © 2014 John Wiley & Sons, Inc. All rights reserved.. 15-1. Simple Harmonic Motion. 15.01 . Distinguish simple harmonic motion from other types of periodic motion.. 15.02 . University of Michigan. Physics Department. Mechanics and Sound . Intro . Labs. Simple Harmonic Motion. This week you move away from rotational motion and begin to study simple harmonic motion. We say that you move away from rotational motion only in the sense that you will not be studying rotating objects as the main focus of the lab. However, it is worth noting that several concepts from rotational motion can be related to simple harmonic motion. You will study three simple harmonic oscillators today: the mass and spring system, the simple pendulum, and the ball and dish oscillator.. deal mainly with . simple harmonic. oscillations where the position of the object is specified by a . sinusoidal. function. . Mass on a spring. Energy. Pendulum. Chapter 15: Oscillatory motion. Reading assignment: Chapter 15.1 to 15.5; 15.6 & 15.7 cursory . Please pick the Learning Outcomes from the front of the room. Take a moment to review the Learning Outcomes. A Couple Things…. This is an EXTREMELY . quick. and somewhat . easy. unit (3 classes). © 2014 Pearson Education, Inc.. Contents of Chapter 11. Simple Harmonic . Motion—Spring . Oscillations. Energy . in Simple Harmonic Motion. The . Period and Sinusoidal Nature of SHM. The . Simple Pendulum. Oscillations. © 2014 Pearson Education, Inc.. If an object vibrates or oscillates back and forth over the same path, each cycle taking the same amount of time, the motion is called periodic. The mass and spring system is a useful model for a periodic system. Hooke’s Law. When a spring is stretched, a restoring force is created.. The restoring force is proportional to the displacement . The restoring force is always directed toward the equilibrium point. Explain how force, velocity, and acceleration change as an object vibrates with simple harmonic motion.. Calculate the spring force using Hooke’s law.. OBJECTIVES. What is periodic motion?. A repeated motion (e.g. pendulum swinging) that is back and forth over the same path.. Oscillations. © 2014 Pearson Education, Inc.. If an object vibrates or oscillates back and forth over the same path, each cycle taking the same amount of time, the motion is called periodic. The mass and spring system is a useful model for a periodic system. This Slideshow was developed to accompany the textbook. OpenStax. Physics.
