ByA 0.4 kg basketball bounces off the ground. The ball’s speed the moment it hits the ground is 20 ms -1 . The ball’s speed the moment it leaves the ground is 20 ms -1 . Calculate the ball’s initial momentum Calculate the ball’s final momentum

ByDo now. Vectors. In 1 dimension (1D) we can keep track of direction simply by using + or – signs. In 2 dimensions (2D) or more this is no longer sufficient. –. +. | | | | | |. Vectors. Recall, we have said that vectors have a magnitude and direction. i.e. 325 m east 18 m/s left

ByVector Addition and Subtraction. Position, Displacement, Velocity, Acceleration, Jerk, Jounce (snap, crackle and pop). Vector addition in 1D. Vector Addition in 2D: Parallelogram and Tip to Tail Methods. Vector subtraction, two methods. Trig method: On Black Board after tutorial.

ByVectors. A vector is a quantity that is characterized by both magnitude and direction. Vectors are represented by arrows. The length of the arrow represents magnitude. The direction of the arrow represents direction.

ByVectors vs. Scalars Pop Quiz: Which of these do you think are vector quantities? Mass, Temperature, Distance, Displacement, Speed, Velocity, Acceleration, Force, Work, Energy, Power, Momentum, Time. A vector is an arrowed line. A vector has a tail and a head .

ByVectors and Two-Dimensional Motion. Vector Notation. When handwritten, use an arrow: When printed, will be in bold print: A When dealing with just the magnitude of a vector in print, an italic letter will be used: A. Properties of Vectors. Equality of Two Vectors

ByChapter 3.1-3.2. Vectors. Vector vs. Scalar Review (3.1). All physical quantities encountered in this text will be either a scalar or a vector A vector quantity has both magnitude (size) and direction A scalar is completely specified by only a magnitude (size). Vector Notation.

ByLecture 2: Vectors 向量 (chapter 3 of Halliday). A vector has both magnitude and direction, e.g. displacement is a vector. But some physical quantities are not vectors, they are scalars, e.g. temperature, mass, time, density, etc….

ByIntroduction to Vectors. UNIT 1. What is a Vector? . A vector is a directed line segment, can be represented as AB or AB, where A and B are the two endpoints of the line segment. Directed means that the vector has a direction. QUESTION: Which direction is implied for vector AB?.

ByProperties of Vectors. Equality of Two Vectors Two vectors are equal if they have the same magnitude and the same direction Movement of vectors in a diagram Any vector can be moved parallel to itself without being affected Relevant for vector algebra (like subtracting vectors).

ByVectors vs. Scalars Pop Quiz: Which of these do you think are vector quantities? Mass, Temperature, Distance, Displacement, Speed, Velocity, Acceleration, Force, Work, Energy, Power, Momentum, Time. A vector is an arrowed line. A vector has a tail and a head .

ByLecture 4. Today: Chapter 3 Introduce scalars and vectors Perform basic vector algebra (addition and subtraction) Interconvert between Cartesian & Polar coordinates. Finish. Start. q. q. 9.8 m. 9.8 m. An “interesting” 1D motion problem: A race.

ByVectors. You will be tested on your ability to: correctly express a vector as a magnitude and a direction break vectors into their components add and multiply vectors apply concepts of vectors to linear motion equations (ch. 2). Vector vs. Scalar.

ByLecture 4. Today: Ch. 3 (all) & Ch. 4 (start) Perform vector algebra (addition and subtraction) Interconvert between Cartesian and Polar coordinates Work with 2D motion Deconstruct motion into x & y or parallel & perpendicular Obtain velocities Obtain accelerations

ByPHY 113 A General Physics I 9-9:50 AM MWF Olin 101 Plan for Lecture 4: Chapter 3 – Vectors Abstract notion of vectors Displacement vectors Other examples. iclicker question Have you attended a tutoring session yet? Have you attended a lab session yet?

ByUsing Vectors. Two Displacements. A hiker walks east from camp for 2.0 km, then northeast for 3.0 km. What is the final displacement of the hiker? Each individual displacement is a vector that can be represented by an arrow. 3.0 km. 2.0 km. The two vectors can be added graphically.
