... and imagination; there remains lots of unexplored intellectual terrain. Teaching introductory physics, I try to convince students to embrace confusion and uncertainty. I tell them that physicists are professional learners and that being confused for a physicist is like breathing hard for a runner: It's what...

... covered (in a fixed amount of time)? Student C: Greater acceleration at the beginning of the race will produce greater speeds; thus, runner A will cover a greater distance during the acceleration period. Given that the rest of the race is essentially identical for the two, Sprinter A will win...

... molding. Shear is generated because runners and sprues are present. This allows heat to travel to the cavities and promotes crosslinking. The molds on transfer molding machines are usually opened vertically as well. With transfer-molded components, there is no flash since the muld is closed and clamped...

... the “velocity for interval” column. In this activity you will not need to find the “change in speed between intervals” or the “acceleration between intervals” values. Position #1 will be considered to be the origin, so the first interval for the runner to get up to “cruising speed” is not included. Find...

... of a student” course showing timers (x), teacher (T), starting point of constant speed runner (R) and constant acceleration starting point (A). Fig. 2. Typical position-time graph of student trying to maintain a constant speed. To take a set of data the teacher blows a whistle to start all stopwatches...

.... The distance vs. time graph is a direct squared relationship and resembles a parabola. What does it mean to accelerate in terms of distance and time? What is the shape of the distance vs. time graph? If the walker/runner moves with a constant acceleration, how do the times for each distance interval compare...

... meterstick stopwatch level straight area Procedure Five students with stopwatches should stand at uniform intervals of from 1 to 3 meters. The student who is running begins at the starting line. When the runner is ready to start, he or she shouts, “Go!” All timers start their stopwatches...

.... It may be helpful to ask how the results would be different if Adam “race walked” (keeping one foot on the train at all times) instead of running on the train. Usually a few students need to examine this issue carefully to realize that the train does not move out from under the runner while both feet...

.... __________ The coyote is looking for the road runner on his vacation to the Moon. He comes to a cliff overhanging a 100 meter drop. Suddenly, the overhanging rock cracks and breaks off with the coyote on it. Which has more force acting on it while on the way down, the rock or the coyote? Explain what inertia has to do...

...” or the “acceleration between intervals” values. Position #1 will be considered to be the origin, so the first interval for the runner to get up to “cruising speed” is not included. Find the magnitude of the overall average speed in meters/second by averaging the “speed in interval” column. Express this answer...
