Which of these two balls strike the ground first? ________ 4. Compare the two diagrams - the vertical free-fall motion on the left and the two-dimensional freefall motion on the right. Describe t Attention span- . the length of time a person can concentrate on one thing. Cooperative play- . playing together with one or two children and sharing toys. Group play- . play with several children, especially those their own age. If you related the position of the runner to the background in each frame taken in 1 second intervals, you would conclude that the student is in motion.. This series of images, taken at regular intervals, creates a motion diagram for the change in the student’s state of motion.. Lecture 2: . Units . and . Vectors. Kinematics. Checklist. Yesterday:. Homework for Chapter 1 submitted via Mastering. Pre-lectures and check-points completed before 8:00AM today. Wednesday:. Pre-lectures and checkpoints for 1-Dim motion. Chapter 4 Lesson I. The one with the greater mass, because KE=1/2 mv. 2. Question 1. Two books with different masses fall off the same bookshelf. As they fall which has more kinetic energy and why?. Vectors, Shmectors. Objectives. 1. Distinguish between a scalar and a vector.. 2. Add and subtract vectors by using the graphical method.. 3. Multiply and divide vectors by scalars.. Vectors, Schmectors. Vidhya Vijayakumar. Multimedia Processing Lab. MSEE, University of Texas @ Arlington. . vidhya.vijayakumar@mavs.uta.edu. Guided by Dr.K.R. Rao. If you related the position of the runner to the background in each frame taken in 1 second intervals, you would conclude that the student is in motion.. This series of images, taken at regular intervals, creates a motion diagram for the change in the student’s state of motion.. 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?. 1. Changing Units. Speed of a car is 80 miles/hour. What is it in m/s. Multiply by 1 so units cancel and correct units are left. In units of m/s: {80 miles * (5280 feet/mile)*(1 m/3.28 feet)}/hour. properties, addition, components of vectors . When you see a vector, think components!. Multiplication of vectors will come in later chapters.. Vectors have . magnitude. and . direction. .. Chapter 3: Vectors. Read Chapter 1.6-1.9. Scalars and Vectors. All measurements are considered to be quantities. In physics, there are 2 types of quantities – . SCALARS. . AND . VECTORS. .. Scalar. quantities have only magnitude.. Mechanics – the study of how objects move and respond to external forces. Kinematics – study of motion with no concern for the cause. Motion. Perceiving motion is instinctive. —. . your . eyes pay more attention to moving objects . Motion in Two Dimensions. Using + or – signs is not always sufficient to fully describe motion in more than one dimension. Vectors can be used to more fully describe motion. Still interested in displacement, velocity, and acceleration.
