PPT-Velocity/Acceleration Vector vs. Scalar Quantities

A vector quantity is a quantity that has both magnitude and direction Velocity acceleration and force are examples of vector quantities A scalar quantity is a quantity that has magnitude but no direction Time mass volume and speed are examples of scalar quantities. :. Students will be able to:. Describe the motion of a particle traveling along a curved path.. Relate kinematic quantities in terms of the rectangular components of the vectors.. In-Class Activities. What are the different types of motion?. Simple harmonic motion.  a type of . periodic motion.  where the restoring force is directly proportional to the displacement. .. Examples:. Uniform circular . 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. . GENERAL & RECTANGULAR COMPONENTS. Today’s Objectives. :. Students will be able to:. Describe the motion of a particle traveling along a curved path.. Relate kinematic quantities in terms of the rectangular components of the 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. . Vector Quantity. Fully described by both magnitude (number plus units) AND direction. Represented by arrows. -displacement. -velocity. -acceleration. -force. Scalar Quantity. Fully described by magnitude alone. Describe the motion of a particle traveling along a curved path.. Relate kinematic quantities in terms of the rectangular components of the vectors.. In-Class Activities. :. Check . Homework. Reading . Separation of motion in x-and y-direction . Equations for 2-d kinematics at constant acceleration. Projectile motion. Lecture 4: Motion in two dimensions. Velocity. , . .  . Position vector . Know . The definition of scalar and vector quantities. Understand. Concept of distance, displacement, speed and velocity. Be able to . Determine distance and displacement in a given situation with units. Vectors, Scalars, and Motion!. Vector vs. Scalar Quantities. Scalar. . Quantities:. Only has . magnitude . Vector . Quantities:. Have . magnitude. AND . direction. Represented with an arrow. + or – indicates the direction. Displacement, Velocity, and Acceleration are the three vector quantities that describe the motion of any object during a specified time interval.. Vectors – Quantities that have . magnitude . and direction.. 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. 1. Electromagnetism. . Introduction to Electrodynamics. Fourth Edition . David J. .
