questions and answers




perfect inelastic collision - ✔✔ANSW✔✔..👌a collision in
which the objects stick together; most reduction in KE.
momentum is conserved
m1v1+m2v2=(m1+m2)v

Center of Mass (COM) -
✔✔ANSW✔✔..👌comx=(m1x1+m2x2=m3x3...)/(m1+m2+
m3...)
comy=(m1y1+m2y2=m3y3...)/(m1+m2+m3...)

velocity of center of mass - ✔✔ANSW✔✔..👌vcm = (m1v1
+ m2v2)/(m1 + m2)
(total momentum of system)/(total mass of system)
same before and after collision

angular displacement - ✔✔ANSW✔✔..👌change Ø= Øf-
Ø0

, Positive angular displacement -
✔✔ANSW✔✔..👌counterclockwise

negative angular displacement -
✔✔ANSW✔✔..👌clockwise

angular velocity formula - ✔✔ANSW✔✔..👌ω = θ/t

Unit of angular velocity - ✔✔ANSW✔✔..👌rad/s

one revolution - ✔✔ANSW✔✔..👌2π radians

angular acceleration formula - ✔✔ANSW✔✔..👌α = Δω/Δt

tangential acceleration related to angular acceleration -
✔✔ANSW✔✔..👌atangential=rα

tangential velocity related to angular velocity -
✔✔ANSW✔✔..👌v=rω

centripetal acceleration and tangential acceleration -
✔✔ANSW✔✔..👌a(centripetal)=rω^2

net acceleration -
✔✔ANSW✔✔..👌a(net)=r(sqrt(ω^4+α^2))

torque def - ✔✔ANSW✔✔..👌rotational analog of force
