PPT-Speed and Velocity Speed (v):

distance traveled in a given time Speed is a scalar Velocity v change of position over time Velocity is a vector Where Δ means change in or final initial Average speed. What Is Motion?. 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?. 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!). What Is Motion?. 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?. Answers to Fusion . Motion and Speed Answers. Skip 1, 2, and 4—See J#5 Motion Vocabulary. 3 . If an object changes its position, then it is IN MOTION. It is also changing speed and velocity according to the definitions of both. . © 2015 Pearson Education, Inc.. Velocity and Speed. Speed measures only how fast an object moves, but velocity tells us both an object’s speed . and its direction. .. The . velocity defined by Equation 1.2 is called the . Quantities. Units. Vectors. Displacement. Velocity. Acceleration. Kinematics. Graphing Motion in 1-D. Some Physics Quantities. Vector - quantity with both magnitude (size) and direction. Scalar - quantity with magnitude only. Describing changes in velocity, and how fast they occur, is a part of describing motion.. How are changes in velocity described?. The rate at which velocity changes is called. . acceleration.. Scientists can perform artificial transmutations by bombarding atomic nuclei with high-energy particles such as protons, neutrons, or alpha particles.. How are instantaneous speed and average speed different?. . Speed. Average speed is computed for the entire duration of a . trip (includes starts and stops so it slows your rate down), . and instantaneous speed is measured at a particular . Bell Ringer 11-7-13. Compare and Contrast Speed, Velocity and Acceleration. is the speed of an object in a particular direction. MYP Unit Question: What Moves YOU!!. Area of Interaction: Human Ingenuity. Velocity and acceleration Measuring an objects motion speed Speed is calculated by dividing distance by time S = d/t 5.0 km/h 2.5 m/s 45 mph velocity Velocity is the same as speed, but you tell the direction of motion in the answer. 9/18/18. What Is Motion?. 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?. In physics, . velocity . is speed in a . given direction. . . When we say a car travels at 60 km/h, we are specifying its speed. . When we say a car moves at 60 km/h to the . north. , we are specifying its velocity.. Velocity is a vector, speed a scalar. Average speed – total distance divided by time. Average velocity – total displacement divided by time. Speed and velocity may or may not have the same magnitude. Definitions . Speed. : speed of an object is define as the distance traveled by it per unit time .I.e. speed of an object tells us how fast an object moves. Expression for speed : let distance traveled by an object be S in time t .then.
