Answer
Brief Explanations:
- In fast - moving athletic events like skiing, cycling, running, and projectile events, profile drag is indeed the main form of drag. This is due to the shape and orientation of the moving object relative to the fluid (usually air) it is moving through.
- When a body moves on a circular path in the same direction (even if not at the same time instantaneously), it is experiencing angular motion. Angular motion is characterized by movement around a fixed axis in a circular or curved path.
- A stick - figure model is used to represent the total body configuration for gross motor skills that occur in two dimensions. It simplifies the complex human body into basic geometric shapes (lines for limbs etc.) to analyze and understand the movement patterns in 2 - D space.
Answer:
- True
- angular
- stick figure model
