Quantitative Analysis 1, 1, 1 letting your students experiment either before or while they are working average speed. Return to Table of Contents, At t = 0 s , two cars are located at the starting line. (c) Because the normal force is not always the only centripetal force, it alone is not equal to mv2/ R . Teachers who can coach students through such moments, and train them to see S graphs as evidence to support claims or solve problems. Remember, the AP Physics 1 exam has 5 free-response questions, and you will be given 90 minutes to complete the FRQ section. At point b, the track has a radius of 13m and the rider feels four times heavier than normal. EK 3.A, 4.A SP 1, 2. Page 1 of 31. airplane) does not receive any impetus, and so falls straight down. The Answer is C: Both require the same time. sign as the velocity. factual misconceptions can often be easily corrected, insisting that students dismiss The entire time the mass is inside the loop, it must be undergoing centripetal acceleration (specifically, its v2 / R must equal its inward acceleration).
