6.1 Uniform Circular Motion

In Uniform circular motion, its linear speed is constant, while its linear velocity
always changes.

The equation of angle is define by:
𝜃 = 𝜔𝑡
Explanation:
θ
= angle (rad)
ω = angular speed (rad/sec)
t = time (sec)

The relation between the angle and with the path length is define by:
𝑠 = 𝜃𝑅

The relation between angle degree units and radian
360° = 2𝜋 𝑟𝑎𝑑
1 𝑟𝑎𝑑 =

360°
= 57.3°
2𝜋
The relation between linear speed or translational and angular velocity:
𝑠 = 𝜃𝑅
∆𝑠 ∆𝜃
=
𝑅
∆𝑡 ∆𝑡
𝑣 = 𝜔𝑅
Explanation:
ω = angular speed (rad/sec)
v = linear speed (m/s)

In uniform circular motion, there is period T. Period is the time required for one
complete revolution. Meanwhile, angular velocity is an angular magnitude which
is travel distance per unit time. The relation between angular velocity and period
is as follows
𝜔=
2𝜋
𝑜𝑟 𝜔 = 2𝜋𝑓
𝑇
Explanation :
T = period (s)
f = frequency (Hz)

The unit convertion from rps (revolution per second) to rpm (revlution per minute)
1 𝑟𝑝𝑠 = 60 𝑟𝑝𝑚
1 𝑟𝑝𝑠 = 2𝜋

Centripetal Acceleration
The direction of centripetal acceleration always strives to the center. The
centripetal acceleration is formulted

𝑅
6.2 Nonuniform Circular Motion
•
The formulation of speed, path length, and the quantity of traveled angle basically
is equal to the formulation for the regular change rectilinear motion. Linear speed
and length path after t unit of time is formulated as follows
𝜔𝑡 = 𝜔0 + 𝛼𝑡
1
𝜃 = 𝜔0 𝑡 + 𝛼𝑡 2

The relation between the quantity of angular acceleration and linear acceleration is
define by
𝑣 = 𝜔𝑅
