Angular Momentum Flashcards
1
Q
Principle of conservation of angular momentum
A
Angular momentum of a rotating body is conserved unless acted upon by an external torque
2
Q
Angular momentum symbol and units
A
L, Kgm^2s^-1
3
Q
Angular momentum and angular velocity equation
A
L=Iw
Where L is angular momentum in kgm^2s^-1
I is moment of inertia kgm^2
And w is angular velocity in rads^-1
4
Q
Equations involving angular momentum and radius
A
L=mvr and L=mr^2w
5
Q
Ek(rotational)=
A
1/2Iw^2
Where I is moment of inertia in kgm^2
And w is angular velocity it rads^-1
6
Q
Ek(total) equal (two)
A
Ek(rotational)+Ek(translocational)= Ep
