Angular kinematics

Question 1

angular distance

Answer 1

-total length of angular pass

Question 2

angular displacement

Answer 2

-equal in magnitude to the angle difference between initial and final position go object
-anglef-anglei

Question 3

angular speed

Answer 3

angular distance / change in time

Question 4

angular velocity

Answer 4

-angular displacement / change in time
-Af-Ai /t2-t1
-degrees/s

Question 5

angular acceleration

Answer 5

-rate of angular velocity change with respect to no time
-degrees/s^2

Question 6

linear and angular displacement

Answer 6

->radius between a given point on a rotating body and the axis of rotation> linear displacement
-curvilinear distance= radius of rotation

Question 7

relationship between linear and angular velocity

Answer 7

-linear= radius of rotation X angular velocity
-two components
-if I decrease my radius rotation, my angular acceleration will increase

Question 8

relationship between linear and angular acceleration

Answer 8

-object one curved path experiences both linear and angular acceleration simultaneously
-tangenital acceleration
-radial acceleration

Question 9

tangenital

Answer 9

-time rate change in linear velocity as accelerate along curved path
-(linear velocity f- linear velocity i)/ change in time

Question 10

increasing tangential acceleration

Answer 10

-radius of rotation X angular acceleration
-shpuld be max before release

Question 11

radial acceleration

Answer 11

-rate of change in direction of a rotating body as moves along curved path
-restraining force
>centripetal force
>centrifugal force
>radial acceleration: (linear velocity)^2/ radius of rotation
