Rolling shutter scans across the scene so that not all parts of the scene are captured at the same time. This small delay adds blur/distortions to objects that are moving very fast. Some aliasing effects that rolling shutter causes include wobble, skew, spatial aliasing, and temporal aliasing. Wobble, as its name suggests, refers to an image that is captured by a moving/shaky camera. Skew describes the bending of the image that may occur to rolling shutter.
On the other hand, global shutter captures the entire frame all at once.
