rom the instant1 when the particle passes ■A. Let the distance dpof the particle from thediameter after a time, t,be denoted by x, and thecorresponding angle at thecenter by 6. Then the com-ponent of the force Fc toward this diameter will be (54) -Fx = FesmO,where the minus sign denotes that the… … Fig. 40. whence, by substitution of the value of Fc from equation 31. ■iirhnx (56) — Fx= jyi 1 or, (57) Fx 4?r2m ~i~ p2 = const. — HARMOXIC MOTIOX. 59 which shows that in harmonic motion the force variesdirectly as the displacement.
