Circular Motion Flashcards
1
Q
What is the linear velocity of a point moving in a circle?
A
V=rω=rθ/t= arc length/time
2
Q
What is angular velocity?
A
Angular velocity is angular displacement (angle swept out) divided by the time taken. (ω=θ/t)
3
Q
What is centripetal acceleration equal to?
A
a= v^2/r = rω^2
4
Q
What is the centripetal force of an object moving with circular motion?
A
F = mv^2/r = mω^2r
5
Q
Describe the Time Period of an object moving with circular motion.
A
T = 2π/ω
