PPT-Section 1: Displacement, Velocity, and Acceleration

Displacement Is the distance from where you start to where you finish Δ d d f d i Velocity How fast and in what direction vector quantity V dt Speed How fast scalar quantity. Using the equations on the board, answer the following questions on a sheet of paper. . 1. What equation would you use to solve for the height of a building that you drop a penny off of?. 2. What equation would you use to solve for final velocity of a moving car?. One-Dimensional Motion. Mr. Richter. First Quarter Categories. Displacement. Upward Launches. Free Fall. Negative Acceleration. Displacement. A man walks 15 m to his left and then 10 m back to his right. What is his displacement?. Physics 4A . Spring 2015. Chapter 2. Motion Along a Straight Line!. Goals for Chapter 2. Describe . straight-line motion. in terms of . velocity. . and . acceleration. Distinguish between . average. “Jeff”, “Mr Jeff”, “Mr C”, “Ciaccio” (See-ah-co) are all fine.

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. . Chapter 2. Kinematics: Description of Motion. Warmup. : . Movin. ’ On. Acceleration . refers to any change in an object’s velocity. . Velocity . not only refers to an object’s speed but also its direction. The direction of an object’s acceleration is the same as the direction of the force causing it.. Equations of Motion for Constant Resultant Force. Also called ….. because………. …acceleration and resultant force are directly proportional. . s. uvat. equations. Also called ….. (unhelpfully). 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. . Describe the speedometer on a car that is entering a highway, drives for 25 miles and then exits the highway.. Consider the two situations below. When a shuttle bus approaches a stop, the driver begins to apply the brakes to slow down 5.0 s before actually reaching the stop. The speed changes from 9.0 m/s to 0 m/s over time.. 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.. Displacement: . Is the distance from where you start to where you finish. . Δ. d=. d. f. -d. i. Velocity:. How fast and in what direction (vector quantity). V = ∆d/t. Speed: . How fast (scalar quantity). P3 Challenge – Do Now (on slips of . paper. ).
