1 mile = 1609 m Period = 1 / frequency T = 1 / f and f = 1 / T Frequency = number of cycles per time Period = time for one cycle 1 Hz = 1/s = 1 s^-1 Velocity/Acceleration Avg. Speed = total distance / total elapsed time instantaneous time=very short distance / very short time Velocity= change in distance / change in time ( d final – d initial / t final – t initial) Velocity is a vector (Pythagorean) Acceleration = change in velocity / change in time (final speed – initial speed/ change in time) G = 9.8 m/s^2 Centripetal acceleration = v^2 / r a proportional to v^2 velocity inversely proportional to r Constant velocity d = v t Object that starts from rest w/ constant acceleration v = at Slope = change in v / change in t = a Average velocity = (0 + at)/2 distance traveled = 1/2 at x t d = 1/2 at^2 (a constant) If starting w/ velocity v(average) = v(initial) + at/2 d = v(initial)t + at^2 / 2 Force 1 N = .225 lb 1 lb=4.45 N F = ma Weight = mg centripetal force = mv^2/ r Springs k = F/ d * Newton 3 rd law F(B on A) = -F(A on B) Force on two bodys = Gm1*m2 / d^2 G = 6.67x10^-11 N-m^2 / kg^2 g=GM/Radius^2 Linear momentum = mv net exterman force acting on an object= change in momentum(mv)/change in time total mv before = total mv after (in a collision) Two carts w/ spring on 1 v1 / v2 = - m2 / m1 because mv(after) is 0 b/c mv(before) is 0 (they both aren’t moving). Work F on left end/ F on right end = d right end moves / d left end moves Work= Fd 1 joule = 1 newton-meter Work done by gravity = Wd = mgd Constant acceleration = work = Fd = ma * 1/2 at^2 = 1/2m * a^2 * t^2= 1/2m *(at)^2
