rotation

Rotation is very similar to linear movement in the sense that the laws of motion and inertia still apply. For example we discussed in class whether or not the skater was applying a force mid spin. We determined that the skater was not applying force at the time of the spin but instead was relying on the laws of inertia to aid her in her task. Over time even with the most minute amount of friction the rotation will slow and eventually cease. However the rotational movement differs from the linear movement at one key point. The rotational movement doesn't change position.
