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?. Rotational Kinematics. Axis of Rotation . When an object rotates, points on the object, such as . A. , . B. , or . C. , move on circular paths. The centers of the circles form a line that is the axis of rotation.. “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. . SRS Synthesis. 1. . Wavelets. 2. Damped Sinusoids. Wavelet Synthesis. Goal: . Synthesis acceleration time history that can be used for a shaker test or for a numerical simulation. 3. Shaker Shock. Oscillation. Simple Harmonic Motion. Simple harmonic motion. (SHM) refers an oscillatory, or wave-like motion . where the restoring force is linearly or directly proportional to the displacement from the equilibrium position, and in the opposite direction. . Name: . Hour: . Determine displacement based on distance measurements.. Calculate speed and velocity based on position and elapsed time.. Create and interpret distance-time graphs.. Calculate acceleration based on speed and elapsed time.. 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. 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, 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).
