	Here are some important definitions.
	这些是定义。
	Displacement:
	位移：
	R=Re^jθ
	All particles of a body move in parallel planes and travel by same distance is known as linear displacement.
	物体所有粒子在平行的平面内移动相同距离称为线位移。
	A body rotating about a fixed point in such a way that all particles move in circular path is known as angular displacement.
	物体和它所有的粒子绕固定点沿圆周路径移动称为角位移。
	If we take the first order derivative of the displacement equation, we get:
	位移方程对时间求一阶导数得：
	d/dt(Re^jθ)=R'e^jθ+Re^(jθ)jθ'=R'e^jθ+Rθ'je^jθ
	The angular velocity
	角速度
	w=dθ/dt.
	The linear velocity
	线速度
	v=dR/dt.
	Acceleration, the rate of change of velocity.
	加速度是速度的变化率。
	Now we take the second order derivative of the displacement equation, we get:
	位移方程对时间求二阶导数得：
	d^2/dt^2(Re^jθ)=R''e^jθ+R'θ'je^(jθ)+(Rθ''+R'θ')je^jθ+Rθ'je^(jθ)jθ'=R''e^jθ+2θ'R'je^jθ+θ''Rje^jθ-R(θ'^2)e^jθ
	The angular acceleration
	角加速度
	α=θ''=dw/dt
	The linear acceleration
	线加速度
	a=R''=dv/dt
	Here's a simple case.
	举个栗子。
