PPT-Average Speed Practice Problems

KMS 8 th Grade Science 1 Mae took a nonstop flight to visit her grandmother The 750 mile trip took 3 hours and 45 minutes or 375 hours Because of the bad weather the return trip took four hours and 45 minutes or 475 hours What was her average speed for the round trip. 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?. I can understand the problem.. I can try different strategies until I solve the problem.. I can keep thinking until I solve the problem.. Practice 2- Reason Abstractly and Quantitatively . I can use math to represent solutions.. 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. . Dimensional Analysis, Speed, Velocity, Acceleration and Free Fall. Review Outline:. Dimensional Analysis Problems (converting). What is speed?. Calculations using speed formula.. What is velocity? . Top . mathematicians think . slowly and deeply.. Mastery. What is Mastery?. There are generally four ways in which the term mastery is being used in the current debate about raising standards in . mathematics:. 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.. 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. 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. . The mathematics of continuous change. Instead of looking at average or overall results, calculus looks at how things change from second to second.. Calculus. The mathematics of continuous change. Instead of looking at average or overall results, calculus looks at how things change from second to second.. 1.Superman is off to visit Lois Lane. He sees he’s late and increases his flying speed. I know he defies the laws of physics anyway, but let’s pretend, okay? If our lead-phobic super hero accelerates uniformly from 1200 m/s to 1600 m/s in 0.40 seconds, then what is his rate of acceleration? . 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 . 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. 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. 1.. 1. In aviation, a "standard turn" for a level flight of a propeller-type plane is one in which the plane makes a complete circular turn in 2.00 minutes. If the speed of the plane is 170 m/s,. a. What is the radius of the circle? .
