If an object rotates around its center point, it is called rotational speed. If the motion of an object is along a straight line, then this motion is called motion motion. If a particle with periodic motion moves in a certain direction for half of its period and in the opposite direction for the rest of the time, then its motion is called vibrational motion. Vibration speed is also called oscillation speed. In the case of rotational motion, the object continues to revolve around its center point. In the case of motion, the object moves forward to move from one point to another. In the case of oscillation motion, the object is reversed during one period and reversed the other half.
