PPT-Initial Approach to Acceleration

English 360 Focused English Fundamentals The California Acceleration Project CAP supports colleges to increase student completion of transferlevel English and math through evidencebased practices that reduce or eliminate students time in remediation. Mouse Trap Cars . What is a Force. Def. - . cause physical change. Ex – Friction and gravity . Forces are measured in . Newtons. , N . Mass. Def. – How much matter an object has. Ex. – Weight . 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?. According to Google maps, one can get from Ms. . Poole’s house . to the . Georgia Dome . (about . 3 miles. ) in 10 minutes. What average speed are the map makers assuming we travel. ?. (Show ALL work!). Objectives:. Learn the 4 motion equations for 1 dimensional motion . when acceleration is constant. a = . Δ. v. Δ. t. 1. . Kinematics . Equation 1. Motion at Constant Acceleration. but since "Δ" means change. a = 0 . case. no . acceleration  velocity is constant  v = . v. i. position . vs. time  . x. f. . = x . i. . + . v . t,. . x. i. . is the starting . position. acceleration = a = constant. WE CAN ONLY USE THESE IN ONE DIRECTION AT A TIME . (only X or only Y not both at same time). Equation 1. Where . V. f. . = Final Velocity. V. 0 . = . Initial Velocity. a. = Acceleration. t = Time. Equation 2. for 3D MHD simulations. Ulyanov Artem, LPI RAS, Moscow. a. rtem.ulianov@gmail.com. Russian-British Seminar of Young Scientists “Dynamical plasma processes in the heliosphere: from the Sun to the Earth”. 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.. u. ndergoes a constant acceleration of 10. m/s/s.. How far will the car travel in 3.0 s?. How fast will the car move in 3.0 s? . Do Now. Starting from rest, a car . u. ndergoes a constant acceleration of 10 m/s/s.. Acceleration is a change in velocity. Speed or direction. Centripetal Acceleration. Acceleration can mean a change in direction, not just speed. Centripetal acceleration. Acceleration that occurs in a circular motion. Acceleration is a measure of . the change in velocity per unit of time. When the velocity of an object is changing, it is . accelerating. Negative acceleration: . slowing down. Positive acceleration: . Velocity . Is a description of an object’s . speed . and direction. .. formula is the same as for speed. . . Velocity= . Distance. . in one direction. Time. Speed vs. Velocity. What is acceleration?. If you’re traveling in a car at a constant speed of 50 mph, are you accelerating?. No, you’re not. . Acceleration is the rate of change of velocity. . Acceleration. In order for acceleration to occur, velocity MUST be . 3.2. 3.2 Acceleration. Think about a car at a stop light. When the light turns green, the car starts moving and the car’s velocity increased. The car began accelerating. Acceleration is the change in velocity divided by the time it took the change to occur.
