We will study more on this in a few weeks. For now just know that our shutter can control the motion in our subject. When the shutter is left open for a longer time (like 1/30 or 1/60) the object can move farther during the exposure which will cause a blur. Fast shutter speeds keep the subject from moving and freeze the motion. The key here is in being aware of motion on your first shots and asking yourself....would this look better frozen or as a blur? Then pick the shutter speed.
