Rotational Motion Flashcards
1
Q
Radians
A
Theta=l/r
2
Q
2 pi radians equals
A
360 degrees
3
Q
Angular position
A
Theta (radians)
4
Q
Angular velocity
A
Omega (rad/s)
5
Q
Angular acceleration
A
Alpha (rad/sec^2)
6
Q
Tangential Velocity
A
v=r *omega
7
Q
Tangential Acceleration
A
a=r*alpha
8
Q
Radial acceleration vs Tangential acceleration
A
Radial goes in a circle
Tangential speeds up a spot, affects angular velocity
9
Q
Angular velocity equals
A
2pif
10
Q
Radial Acceleration
A
a=【(v)^2】/r = r*(omega)^2
11
Q
Net Torque
A
T net=I*alpha
12
Q
Moment of Inertia
A
I=(sum) mr^2
13
Q
Torque
A
T=RF(perpendicular)
T=R(perpendicular) F
14
Q
Rotational Kinetic Energy
A
K=1/2(I)(omega) ^2
15
Q
Velocity while rolling without slipping
A
Vcm=R(omega)
