to represent the total body configuration for gross motor skills that occur in two dimensions, a is used.
stick figure model
particle model
rigid body segment model
response diagram

Explanation:

1. When all parts of a body move the same distance, in the same direction and at the same time, it is called translational motion. This is a basic concept in the study of motion in physics.
2. When gravity is the only external - force acting on a projectile, its center of mass follows a parabolic path. This is due to the combination of the horizontal (constant - velocity) and vertical (constant - acceleration due to gravity) components of its motion.
3. A stick - figure model is used to represent the total body configuration for gross motor skills that occur in two dimensions. It simplifies the body into basic line - like segments to show the overall movement pattern.

Answer:

Question 1: Translational
Question 2: Parabolic
Question 3: Stick figure model
