Coupled Motion. Coupled motion problems are problems in which the movement of one object directly impacts the motion of another object.. We have already briefly covered this topic when talking about pulleys.. Physics . (PYPY001. ). Coordinator:. . Prof.Dr.Hassan. . A.Mohammed. Preparatory Physics . PYPY001. . Physical science . is concerned with making sense out of the physical environment.. Objects. Equations for uniform acceleration. Where. s. is displacement (m). v. is the final velocity (m s. -1. ). u . is the initial velocity (m s. -1. ). a. is the acceleration (m s. -2. ). Equations of Motion for Constant Resultant Force. Also called ….. because………. …acceleration and resultant force are directly proportional. . s. uvat. equations. Also called ….. (unhelpfully). In some cases, we will have to decompose a vector into a sum of two separate vectors. Recall; most vectors may be written as some variation of the special unit vectors {1,0} and {0,1}. With vectors, sometimes they may not be pointing or oriented in the proper direction. 1. A system of objects that are not moving with respect to one another. Used to determine the motion of an object.. Frame of Reference. 2. If you were measuring the length of a lunch tray you would most likely label it with the following unit.. Chapter 2. The stuff you should know:. Laws of Motion. Finding resultant forces. In 2D. Non-orthogonal axes. Law of Sines, Law of Cosines, Parallelogram law, Head to Tail Addition. Orthogonal. Add Cartesian Vectors(especially if more than 3 forces). What is motion?. Motion . is . when an object changes its . position. .. Motion . can be represented mathematically through calculations of . speed, velocity, and . acceleration. Motion is . when an object changes its position. (1) a book resting on a table, . (2) a hockey puck sliding with constant velocity across a frictionless surface, . (3) the rotating blades of a ceiling fan, and . (4) the wheel of a bicycle that is traveling along a straight path at constant speed. . Chapter 3 pg. . 81-105. What do you think?. How are measurements such as mass and volume different from measurements such as velocity and acceleration?. How can you add two velocities that are in different directions?. Today’s Objectives: Students will be able to: Apply Newton’s second law to determine forces and accelerations for particles in rectilinear motion. In-Class Activities: Check Homework Reading Quiz Force and Motion Basketball Review Game Game Rules If your team gets the question right, you get a chance to shoot the ball into the hoop. If you get the ball in the hoop, each person on your team wins a piece of candy. Lecture 1. Basic Quantities. Length: is used to locate the position of a point in space and thereby describe the size.. Time: is conceived as a succession of events .. Mass: is a measure of a quantity of matter that is used to compare the action of one body with that of another.. 2017-2018 . Mr. Mohammed Tareq. Petroleum and Mining Engineering Department . .
