Refers to the orientation of a line with another line or plane.
What is angular position?
100
Imaginary plane running side to side and superior and inferior dividing the body into anterior (front) and posterior (back) parts.
What is frontal, coronal, or lateral plane?
100

Sasha Cohen does a triple toe loop and rotates three times around in 1 s. What is her average angular speed during this jump?
3 rev/s
100
This animal consumes water by making its tongue into a ladle-like shape and scoops water to itself.
What is a dog?
200
A unit of measure for an angle that is the ratio of the arc length divided by the radius.
What is radians?
200
Imaginary plane running anterior (front) to posterior (back).
What is anteroposterior plane or sagittal plane?
200
Dale Earnhardt Sr. (may he rest in peace) won the Daytona 500 and began burning rubber on the track. His rear wheels spun 40 revolutions per second. What is this in radians per second?
80 pi radians/s or 251.2 radians/s.
200
During a discus throw, Anthony's arm rotates 20 rad/s, and the discus is 1.5 m from the axis of rotation when he releases it. John's arm rotates 30 rad/s, and the discus is 1.1 m from the axis of rotation when he releases it. Whose discus throw is most likely to be farther?
John's

This animal has essentially 9 brains, 3 hearts, and blue blood.
What is an octopus? 
300
The change in absolute angular position experienced by a rotating line.
What is angular displacement?
300
Imaginary plane that runs side to side and anterior to posterior horizontally and divides the body into superior and inferior parts.
What is transverse or horizontal plane?
300
What is the average angular velocity of an object moving through 60° in 2 s?
Angular velocity = 30°/s
300
During a drive by golfer Ai Miyazato, the angular velocity of her club is zero at the top of the backswing and 30 rad/s at the bottom of the downswing just before impact with the ball. If the downswing lasts 0.30 s, what is the average angular acceleration of the club during the downswing?
100 rad/s2

This is the smallest national park in the United States.
What is the gateway arch of St Louis?
400
The rate of change of angular displacement.
What is angular velocity?
400
The component of linear acceleration tangent to the circular path of a point on a rotating object.
What is tangential acceleration?
400
Mike runs in lane one around a curve, while Maurice runs in lane eight around a curve. The radius of lane eight is twice as big as the radius of lane one. If Mike has to run 50 m to get fully around the curve in lane one, how far does Maurice have to run to get fully around the curve in lane eight?
hint: arc length (s) = rΔθ
arc length = 100 m

During Charlie’s golf drive, the angular velocity of his club is zero at the top of the backswing and 20 rad/s at the bottom of the downswing just before ball impact. The downswing lasts 0.20 s, and the distance from the club head to the axis of rotation is 2.0 m at the bottom of the downswing. a) What is the average angular acceleration of the club during the downswing? b) What is the linear velocity of the club head just before impact with the ball?
a) 100 rad/s2
b) 40 m/s
400
This animal's heart differs in where it lives in the body based on the type of habitation this animal lives in -- in trees, the heart is closer to the head, while on the ground, its heart is further down the body.
What is a snake?
500
The rate of change of angular velocity.
What is angular acceleration?
500
The component of linear acceleration that is directed towards the center of the circle (towards axis of rotation).
What is centripetal acceleration?
500
During Charlie’s golf drive, the angular velocity of his club is zero at the top of the backswing and 20 rad/s at the bottom of the downswing just before ball impact. The downswing lasts 0.20 s, and the distance from the club head to the axis of rotation is 2.0 m at the bottom of the downswing. a) What is the average angular acceleration of the club during the downswing? b) What is the linear velocity of the club head just before impact with the ball?
ωi = 0 rad/s, ωf = 20 rad/s, Δt = 0.20 s, r = 2.0m
a) α = ωf - ωi /Δt = (20 rad/s - 0)/0.20 s = 100 rad/s2
b) V = ωr = 20 rad/s*2.0 m = 40 m/s
500
A hammer thrower, Brandon, spins with an angular velocity of 1200°/s. The distance from his axis of rotation to the hammer head is 1.2 m. a) What is the linear velocity of the hammer head? b) What is the centripetal acceleration of the hammer head?
a) 25.1 m/s
b) 524-525 m/s2
