Study Notes

Speed is a scalar quantity that measures how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
Velocity uses displacement instead of distance because it accounts for direction, unlike speed which does not.
Average speed considers the total distance traveled over a given period of time.
Waves are periodic disturbances that carry energy through a medium, examples include earthquakes, sounds, x-rays, and colors.
Waves can be classified into transverse waves (move perpendicular to the direction of wave motion), longitudinal waves (move parallel to the direction of wave motion), surface waves (circular motion), mechanical waves (require a medium to propagate), and electromagnetic waves (do not require a medium to propagate).
