Document Summary
Phys-1010q - lecture 2 - intro & motion (ch 1. The red cover edition of the textbook from the uconn bookstore is correct. Many questions will be copied from the homework. Ex. (cid:862)with respect to hartford, uco(cid:374)(cid:374) is 30 (cid:373)iles east. (cid:863) Symbol: x, r, (x and r are most commonly used: speed. = xf - xi / tf - ti ( (cid:373)ea(cid:374)s (cid:862)cha(cid:374)ge(cid:863)(cid:895) (f = final , i = initial: = d/t t = d/s, acceleration. Symbol: a or a: math: a = v/ t, instantaneous speed. Still d/t, except you measure it over the smallest time interval you can measure. Sample questions: you traveled from storrs to greenwich, a distance of 100 miles in two hours. If you were to continue at the same average speed for twice as long, how far would you travel: 50 miles, 100 miles, 200 miles, 400 miles (cid:862)ho(cid:449) far(cid:863) = need to sol(cid:448)e for dista(cid:374)ce. = d/t d= s * t.
