Terms
The line from the center of the circle to the end
What is a radius?
Convert 180 degrees to radians
Pi radians
A point rotates 4/5 pi radians in 0.7 seconds. This is the angular velocity
What is 1.76 rad/sec?
A circle has an angular velocity of 1.35 rad/sec. If the radius is 3.2 meters, this is the linear velocity
What is 4.32 m/s?
The velocity of a point rotating around a center
1/7 pi radians to degrees
25.7 degrees
A point rotates 47/24 pi radians in 3.1 seconds. This is the angular velocity
What is 1.98 rad/sed
A point 5.85 meters from the center rotates at 5/7 rad/seconds. What is the linear velocity?
What is 4.2 m/s?
An object rotates around a circle 5 times in 1.5 seconds. This is the angular veolcity
What is 20.9 rad/sec
The point around which a circle rotates
What is the axis of rotation
6/7 pi radians to degrees
154.3 degrees
A point rotates 123 degrees in 2.7 seconds. This is the angular velocity
What is 0.68 rad/sec?
A point on a circle has a linear velocity of 495 m/s. If the angular velocity is 3 rad/sec, this is the circle's radius
What is 165 m?
The term for velocity perpendicular to a wheel
What is tangential velocity?
136 degrees to radians
34/45 pi (0.76 pi)
A point rotates 355 degrees in 0.37 seconds. This is the angular velocity
What is 16.7 rad/sec?
A point 85 meters from the center is rotating. If it travels 7/4 pi radians over 18 seconds, this is the linear velocity
What is 25.9 m/s?
This direction is positive for angular motion
What is counterclockwise?
