Question | Answer |
angular motion | All parts of a body move through the same angle, in the same direction in the same time |
Joint or relative angles | Angle formed from he long axes of two adjacent body segments |
Sentimental angles or absolute angles | orientation of a single body segment with a fixed line of reference |
Measurement of angular velocity | ω = 0f - 0i / Δt = Δ0 / Δt |
Radian | angle subtended by an Arc = in length to the radius |
Arc length | r0 |
Circumference | 2 π r |
Relationship between linear & angular velocity | V = r ω |
How do you define angular velocity? | Rate of change in the joint velocity ω = Δ ϴ / Δt |
Angular acceleration | Rate of change in angular velocity α = Δ ω / Δ t |
Linear velocity units | m/s |
Angular velocity units | rad/s |
Linear acceleration units | m/s^2 |
Angular acceleration units | rad/s^2 |
If Omega is constant... | no rate of change (alpha - 0) |
Force center of the circle that creates radial acceleration | constant velocity = increase acceleration |
Centrifugal force | reaction from "center-fleeing" force |
Centripetal force | Keeping rotation "center-seeking" |
