After you have filled in each blank use the words to fill in the crossword. Acceleration Dimensional Gravity Position Change Direction Horizontal Starting Constant Displacement Kinematic Time Curve Divide Math Velocity Delta Graphs Naught Vertical Time, position, velocity and acceleration are linked together by the equations [12 down] A car driving on a straight highway is a good example of one motion [13 across] Physicists measure motion with [7 down] The four main conditions of motion are time velocity, and acceleration [10 down] tells you how long you were driving for [5 down] The change in position is known as [9 across] Your is how much your position changes over time; it's different from speed because it also includes a [3 across | 16 down] How your velocity changes is the last quality of motion: [15 down] Physicists visualize motion using [2 across] axis. Graphs usually show position on the axis and time on the [8 down | 11 across] If you want to find your average velocity you have to take the change in position and it by the change in time. [17 across] 2018 Rachel KardellWe abbrevi To find the change in a value you take the final value and subtract the starting value ith the uppercase Greek letter [16 across] breviate this with the Constant acceleration is equal to the in velocity divided by the change in time . [1 across ] The Definition of Acceleration v= votat When something falls, the force of makes it accelerate at 9.81 m/s2. We call that "small g" [2 down | 4 down] The second kinematic equation is called the displacement and is used to find your total displacement. [1 down] To use the second kinematic equation you need to know your acceleration, velocity, and time. [6 down] The Displacement Curve X-XO= Vot+1/204+2 Starting velocity is sometimes called initial velocity or V (Vo) [14 across]Review Questions 1. What the difference between speed and velocity? 2. If you are driving at a constant velocity of 5 m/s what is your acceleration? 3. How is acceleration different from speed? 4. What are the two main kinematic equations? (name and formula) 5. What letter represents change, and how do we calculate it?Name: Date: Period: Crash Course Physics #1: Motion in a Straight Line 3 5 8 10 11 12 13 14 15 16 17 2018 Rachel Kardell
