Unit 3 Flashcards
1
Q
What is centripetal acceleration?
A
Acceleration pointing towards the center, always changing!
2
Q
What is tangential acceleration?
A
Same direction as velocity, on the outer edge of a rotating circle. Determines is angular velocity is increasing or decreasing or staying constant
3
Q
Right hand rule?
A
Turning counter clockwise is positive
4
Q
Radians = S/r, angle?
A
57.3 degrees
5
Q
How many defined eq’s for torque?
A
2
6
Q
Torque open or x’ed?
A
Depends on what you defined as the positive direction for torque
7

A
Scalar
Counter clock wise
Radians
k ihat
8
Q
Angular velocity stuff?
A
Vector
Rad/s
9
Q
Angular acceleration stuff?
A
Vector
Rad/s^2
10
Q
Two types of static equilibrium?
A
Rotational and translational
Both equal zero in this state
