general motion Flashcards
1
Q
What is the radius of rotation?
A
linear distance from point of interest to to the axis of rotation
2
Q
radius of gyration
A
how bunched up weight is to axis of rotation (^rad of gyr = ^ ditribution = sllower spin, decreased rad of gyr = faster spin
3
Q
general motion
A
combination of linear and angular movement e.g. baseball spinning and translating through air
4
Q
differentiate tangential accelleration, radial accel, total accel
A
tangential reflects path of travel if you were to let go of rotating object
radial (centripetal) represents force directing towards the centre of the rotation
total is linear value shown in m/s^2
