Before, we just had kinematics implying one or two dimensional linear movement. Now, we have rotational dynamics, which will be very similar, only now our movement is in a circular shape. Here, youll learn more about angular velocity and acceleration, and how they correlate to their linear counterparts. Your mind should be well accustomed to the concepts of these elements, so the best thing to do is to go through the examples in the video and really ensure that you get the math down, as rotational dynamics is going to start picking up pace in the coming videos.
Once around a circle is 360 degrees, or two pi radians. A radian measures a distance around an arc equal to the length of the arc’s radius.
Linear position is given by the r vector. The position around a curved path is represented by s. Angular positions / displacements are given by theta (θ).
The linear displacement can be found by multiplying the angular displacement by the radius.
Linear speed / velocity is given by the v vector. Angular speed and velocity are represented by omega (ω).
Linear acceleration is given by the a vector. Angular acceleration is given by alpha (α).
Translational (linear) kinematics parallels rotational kinematics. Equations for one mirror the equations for the other.
