      __________ is the distance between elbow to the tip of the middle finger.
    Draw a concept map on types of motion.

Dear Student,

1. The plucked string of sitar shows oscillatory motion. 

The oscillatory motion refers to the motion in which the object moves back and forth repeatedly about a point called mean position. This is a periodic motion which repeats after some interval of time called the period of oscillation. Therefore, oscillatory motion is a motion that is repetitive and which repeats about a mean position.

2. FPS refers to Foot-pound-second, the imperial units system of measurement. Unit of mass is pounds, denoted by lbm.

3. A cubit is a measure of the distance between elbow to the tip of the middle finger. 1 cubit = 18 inches.
