Comparison b/w rotational and Translational motion
TRANSLATIONAL .........................................................ROTATIONAL
1)Linear disp. = x........................................................Angular disp. =
2)Linear speed= dx/dt.................................................angular speed = d
/dt
3)Mass = inertia........................................................Moment of inertia = I
4)linear acc. = a........................................................angular acc.=
5)Linear momentum = p............................................ang. mom. =L
6)Force = m.a..........................................................torque = r x f
7)K.E. = 1/2mv2......................................................R.E. = L2/2 I=1/2Iw2
8)power = F.V........................................................Power = torque x omega
9)s = ut + 1/2at
2....................................................Q= W
ot + 1/2
t
2
10)v = u + at..........................................................W = W
O +
t
11)v2 - u2 = 2as...................................................W2 - Wo2 = 2alpha theta
12)S
n = u +a/2(2N -1).......................................... (theta)
n = w
o +
/2(2N-1)
....................................................................................................................
If 2 bodies of diff. masses posses same momentum , then the lighter body has greater K.E (in translational)......If 2 bodies of diff. MOI posseses same angular momentum then body having lesser MOI posseses greater R.E
If 2 bodies of diff. masses posses same K.E , then the heavier body has greater momentum (in translational)......If 2 bodies of diff. MOI posseses same R.E then body having greater MOI posseses greater Angular momentum
