Circular motion Flashcards
1
Q
What is the tangential and radial component for angular acceleration in circular motion with variable speed?
A
Tangential is rw^dot.Radial is -w^2r.
2
Q
What is the tangential and radial component for angular velocity in circular motion with variable speed?
A
Tangential is Wxr.
3
Q
What is free circular motion?
A
This is when we assume there is no tangential component of the centripetal force.
4
Q
When will a particle on a spring leave its circular orbit?
A
This occurs when the string becomes slack and T=0.
5
Q
When will a particle inside or outside a vertical circle leave its circular orbit?
A
This occurs when the reaction force from the surface becomes 0.
