Work-Kinetic Energy Theorem for Rotational Motion
... Relationship to Labs: This unit is supported by Lab 6: Torque and Rotational Equilibrium (kit-based lab). So far, we have covered motion of objects moving in a straight line, changing direction or going around a curve. Now, imagine trying to apply the linear motion analysis to a spinning object. All ...
