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. . Dimensional Analysis, Speed, Velocity, Acceleration and Free Fall. Review Outline:. Dimensional Analysis Problems (converting). What is speed?. Calculations using speed formula.. What is velocity? . Recall from JC maths / science:. Speed and distance are scalars. We use the vector versions, velocity (. ) and displacement (. ):.  . 1. Solve Problems About Linear Motion. only works for constant (or average) velocity.. 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. . Road Trip!. Mr. Manker is traveling to California. . He drives at a constant pace:. 100 miles the first two hours. 210 miles the next three hours. 240 miles the next four hours. Create a graph . showing his . 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 . 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. 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 . different situations. Speed of . Movement. Measuring the speed of a moving object . in . different situations. Objective. The purpose of this activity is to analyze the change in the speed of an object in different situations, creating an hypothesis and proceeding to test it, using the . 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. 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. ?.
