rotational Flashcards
1
Q
linear acceleration and tangential acceleration
A
a= (r-meters)(alpha- rad/s^2)
2
Q
in a rigid body rotate, what changes and what stays the same
A
angular velocity stays the same since all points are the same angle
angular acceleration changes
3
Q
total linear acceleration
A
a= tangential acceleration + centripetal acceleration
4
Q
centripetal acceleration formula in terms of rotation
A
Ar= w^2r
5
Q
frequency formula in terms of rotation
A
f= w/2PI
6
Q
one complete revolution/period
A
1/f (frequency)
7
Q
linear speed
A
v=wr=
