PPT-1 Displacement and Motion Measurement

In the next two lectures we will discuss how to measure various types of displacement and motion These include Linear Displacement Angular Displacement Linear Velocity Angular Velocity Acceleration. The different detection systems provide a similar feel of operation thus allowing users to introduce Smart in various scenes A wide array of informationbased tools is also available which offers new digital sensing styles to users Sensing Variation M. echanics. - the study of the motion of objects. we focus on the language, principles, and laws that describe and explain the motion of objects. Kinematics. is the science of describing the motion of objects using words, diagrams, numbers, graphs, and equations. . Oscillation. Simple Harmonic Motion. Simple harmonic motion. (SHM) refers an oscillatory, or wave-like motion . where the restoring force is linearly or directly proportional to the displacement from the equilibrium position, and in the opposite direction. . Waves. 4.1 Oscillations. Introduction. All motion is either periodic or non-periodic. In . periodic. motion an object repeats its pattern of motion at a fixed interval of time: it is regular and repeated. Wave motion is also periodic and there are many similarities between oscillations and waves; in this topic we will consider the common features but also see that there are differences.. Today’s Learning Objectives. Know the terms in this chapter.. Why is a reference point needed to describe motion?. What is the difference between distance and displacement?. How do you add vectors?. Task 1 . Get into pairs having one person facing the board (Person A) whilst the other faces away (Person B). . Person A will be shown a distance-time graph, they must explain the journey that it shows to Person B. . PHYS 243. Giancoli. , Sec 2-1, 2, 3, 4. © . 2011, . B.J. . Lieb. Analysis of a Race. All distances measured from starting line.. Time measured by a stopwatch from sound of gun.. Initial speed will be zero. . Examples:. Pendulum.. Oscillating spring (either horizontal or vertical) without friction.. Point on a wheel when viewed from above in plane of wheel.. Physics Classroom has a good lesson on simple harmonic motion under Waves, vibrations.. (17528). Sub.Teacher. : Ms. . Nilesha. U. . Patil. . . Pimpri Chinchwad polytechnics. . Chapter No.-02. Displacement & Pressure Measurement . CO- Explain the working of various displacement and pressure measuring transducers. . (. pg. 30-55). Do Now. Why is it important to describe and analyze motion. ?. How fast?. How far?. Slowing/Speeding?. Rest/Constant velocity. What . are some of the different types of motion. ?. Translational – motion along a straight line. Essential Question: How do you calculate the displacement and velocity of an object?. What is mechanics?. The branch of physics concerned with motion and forces.. The subset of mechanics that describes motion without regard to its causes is called kinematics.. Waves. 4.1 Oscillations. Introduction.
