PPT-How Fast? Lesson 4 Velocity vs Speed

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. 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. . 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?. © 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 . largo. very slow and broad, example: . turtle. adagio. slow, faster then largo and slower than andante, example: . koala bear. andante. walking speed, example: . human. moderato. moderate, example. : . 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.) . Know . The definition of scalar and vector quantities. Understand. Concept of distance, displacement, speed and velocity. Be able to . Determine distance and displacement in a given situation with units. 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. 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. Men’s Olympic Speed Skating What is speed skating? Speed skating is a competitive form of ice skating where competitors race each other in travelling a certain distance on skates. Men compete in 500m, 1,000m, 1,500m, 5,000m and a 10,000. In each event, skaters race in pairs against the clock on a standard 400m oval ring. All events are skated once, apart from the 500m, which is skated twice. In this case, the final result is based on the total time of the two races. 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. 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?. 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?.
