PPT-Determining Average Speed

Lab Lesson 5 January A ticker tape is the most commonly used technology for objects moving in a straight line As the object attached to the end of the paper moves it pulls the tape through the timer As the tape moves through the timer dots are recorded at consistent time intervals . Activity. Compare and contrast the following:. Speed and velocity. Distance and displacement. Average speed and instantaneous speed. A cyclist must travel 800 km. How many days will the trip take if the cyclist travels 8 h/day at an average speed of 16 km/h?. 01-APR-2011 2.1.1 Wind Speed m/s 10.5 10.0 9.5 9.0 8.5 8.0 7.5 7.0 6.5 6.0 5.5 5.0 4.5 4.0 4.0 Source: Wind resource estimates developed by AWS Tr Motion. Motion is the change in an object’s position (or location) relative to a . reference point. .. A . reference point . is an object that appears to stay in place.. Sometimes the change in distance from a reference point to an object can be measured. . Impact on Energy. Tyler C. Folsom, PhD, PE. Project Manager, Qi2, . Kent, . WA. Professor, University of Washington, Bothell, WA. Tyler@TFolsom.com. Easy predictions:. Safer roads. Self-driving taxis blur the distinction between public and private transportation. Average Speed?. If you know the distance an object travels in a certain amount of time, you can calculate the speed of the object. . Speed is a type of rate. A rate is a measurement of something that occurs or changes in one unit of time.. 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. . 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 . KMS 8. th. Grade Science. 1.. Mae took a non-stop flight to visit her grandmother. The 750 mile trip took 3 hours and 45 minutes. (or 3.75 hours). Because of the bad weather, the return trip took four hours and 45 minutes ( or 4.75 hours). What was her average speed for the round trip?. Part 4: Cruising and In-flight Decision Making. Bill Elliott and Rand Baldwin. Six Week Agenda. Weather and Preparation (needed skills, glider & instrumentation, biological). Thermals and Triggers. 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. A swim across a lake. A cycle around the lake. The distances covered and times taken for each section are. :. Calculate Don’s average speed in . kilometres. per hour for the swim section.. Calculate Don’s average speed for the entire race.. 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. This resource provides animated demonstrations of the mathematical method.. Check animations and delete slides not needed for your class.. Speed. What common units do we use to measure . speed. ?. Distance.
