PPT-Are you moving? Lecture Notes: Displacement, Velocity, and Acceleration

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. 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?. “Jeff”, “Mr Jeff”, “Mr C”, “Ciaccio” (See-ah-co) are all fine. Summer Physics Bootcamp.

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.. Today’s Learning Objectives. Know the terms in this chapter.. Why is a reference point needed to describe motion?. What is the difference between distance and displacement?. How do you add vectors?. 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.. up a clicker!. Reminder: All lecture notes posted, after lecture, . follow link at:. http://www.hunter.cuny.edu/physics/courses/physics100/spring-2016. Note: . Before the actual lecture, a “Pre-Lecture” is available on line, which is the lecture (more or less) . 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. Mr. Fedell. VT vs. PT graphs. A position-time (PT) graph tells you . where an object is.. A velocity-time graph tells you . how fast it’s moving.. **(VT graphs DO NOT give in position info!)**. When an object stays still for 10s, its velocity is . 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). 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). Homework for Chapter 2. Read Chapter 2.

Students will understand the general relationships among position, velocity, and acceleration for the motion of a particle along a straight line so that given a graph of one of the kinematics quantities, position, velocity, or acceleration, as a function of time, they can:.
