2. Calculation formula of the relationship between peripheral velocity and angular velocity		Symbol description and unit
（1） Circumferential speed	ν=rθπ/(t*180) [m/sec] ν=	r： Radius of gyration　[m]
		θ： Angular displacement [degree]
		t： time　[sec]
（2） angular velocity	ω=θ/t　[ Every time/sec] ω=	θ： Angular displacement [degree]
（2） angular velocity	ω=θ/t　[ Every time/sec] ω=	t： time　[sec]
(3) Circumferential speed	ν=ωrπ/180　[m/sec] ν=	ω： Angular velocity [degree / sec]
(3) Circumferential speed	ν=ωrπ/180　[m/sec] ν=	r： Radius of rotation [m]
