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. Section 3.4a. The difference quotient:. When we let . h. approach 0, we saw the rate at which a function. w. as changing at a particular point . x. …. Definition: Instantaneous Rate of Change. The . 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. . 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.. You can see it on a. . . position time . graph OR. a . velocity time . graph. POSITION v TIME. Velocity is seen by the . slope. Graphing motion. position-time. Section 1 on graph represents biker going forward. 2.7 m/s. 2. While traveling along a highway a driver slows from 24 m/s to 15 m/s in 12 seconds. What is the automobile’s acceleration? (Remember that a negative value indicates a slowing down or deceleration.) . 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 . Essential Question: How do you calculate the displacement and velocity of an object?. What is mechanics?. The branch of physics concerned with motion and forces.. The subset of mechanics that describes motion without regard to its causes is called kinematics.. 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. 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: . 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). 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?. 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.
