Document Summary

Circular motion - movement of an object along the circumference of a circle or rotation along a circular path: u(cid:374)ifor(cid:373): with constant angular rate of rotation and constant speed, non-uniform: with a changing rate of rotation. =(cid:1006)pi r/r= (cid:1006)pi (cid:1005) radia(cid:374) = (cid:1007)(cid:1010)(cid:1004) /(cid:1006) = (cid:894)~(cid:1009)(cid:1011). (cid:1007) (cid:895) Ce(cid:374)tripetal force a(cid:374)d acceleratio(cid:374) (cid:894)newto(cid:374)"s seco(cid:374)d law(cid:895) a=v2/r . The rate of change of its angular displacement with respect to time, Si unit: radian/sec velocity angular : w w = /t= s/rt= (cid:448)/r. = w t= w t t:period => time required for 1 rotation w t= 2pi complete rotation f: frequency => # of rotations/time (si unit = hz) f= 1/t w = 2pi f. Wave number: k (number of cycles per meter) Angular frequency: (radians per second) y acos(2 ( x. Solution: use the waveform equation and write the expression for this wave. We can calculate the velocity with which wave crests are travelling. vwave x t.
