In this video it is shown how
the x
and the y
components of the position vector
r
of the particle vary with time.
Circular motion with constant speed
is called uniform circular
motion.
For constant angular velocity ω
we have for the phase φ
of the position vector
r the relation
φ(t)
= ωt
+ φ0
In the following we will choose
φ0=0
for the phase at the instant
t=0.
