Motion. is when an object changes place or position. To properly describe motion, you need to use the following:. Start and end position?. Movement relative to what?. How far did it go?. NFV . PoC.

(presenter). evelyne.roch@huawei.com. and . Centripetal Force. Acceleration. Speeding up. Slowing down. Changing direction. . Think of spinning an object on the end of a string. How would you describe it to someone?. The easiest thing to say is that it moves in the shape of a circle.. Now. Josh Frieman. Fermilab. and . the University . of Chicago. Progress on Old and New Themes in Cosmology. Avignon, . April 18, 2014. Last Supper. (in earlier version of program). Cosmologists discuss BICEP2 results at PONT banquet. When a Falling Object Accelerates Only Due to Gravity, We Call This…. . Free Fall. Knowing What We Know Now. Why does a brick with twice the amount of mass as another brick not fall twice as fast? . Physics. Turning:. Turning counts as a form of acceleration because the direction of the velocity vector changes.. Turning requires a force that is perpendicular to the current motion of an object.. Optimiz. Objectives. At the end of this session you will . be able to :. State the DOT rules used to calculate a scheduled ETA in . Optimiz. State the Optimiz system default rules used to calculate a scheduled ETA . Minds-On. *this slide is not intended to be shown. in class. Materials: 2 sheets of paper, 1 rubber ball.. Demo: Take 2 identical sheets of paper. Show students they are identical. Crumple one sheet into a ball. Hold out the . Equations of Motion for Constant Resultant Force. Also called ….. because………. …acceleration and resultant force are directly proportional. . s. uvat. equations. Also called ….. (unhelpfully). A . vector quantity. is a quantity that has both magnitude and direction. Velocity, acceleration, and force are examples of vector quantities. . A . scalar quantity. is a quantity that has magnitude, but no direction. Time, mass, volume, and speed are examples of scalar quantities.. 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.

(Assume towards the cushion is the positive direction.). 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 .
