Uniform Circular Motion Formulae

by Notetube Official•91 words•7 views

Quantity	Formula	Unit
Angular velocity	omega = 2pi/T = 2pi*f	rad/s
Linear speed	v = r*omega	m/s
Centripetal acceleration	$a_c$ = $v^2$ /r = r* $omega^2$ = v*omega	m/ $s^2$
Centripetal force	$F_c$ = $mv^2$ /r = mr* $omega^2$	N
Time period	T = 2*pi/omega	s
Frequency	f = 1/T	Hz

Direction: velocity is tangential, acceleration is radial (toward centre), and these are always perpendicular in UCM.
