Ch. 16 - Kinematics of ERO-2D (Extended Rigid Object)
Kinematics (how?) -> Goal: Trying to determine motion (s, v, a, )
For ERO's, motion can be translational and/or rotational
Rectilinear Translation (RT)1.Curvilinear Translation (CT)2.Rotation about a Fixed Axis (Rot)3.General Plane Motion (GPM -> T + R)4.
4 Types of Motion for an ERO-2D:
Rot1.RT2.GPM3.CT4.
Motion:
It take ~6.28 (2) radians to go around the outside of our circle.
How far have we rotated if an object
is undergoing an = 2 rad/s?
Just like T motion, if R has a constant , then we can use the 'Kinematic Equations of Motion.'
(Rot)

Relative QuantitiesvB/A = vB - vA
(sitting in A watching B)
Using Translational Coordinate System -> The X,x and Y,y always remain parallel.
vB/A = vB - vA
Gears:
