Transcribed Image Text:**Instruction for Creating Free-Body Diagrams**
1. **Objective**: Learn how to draw a free-body diagram representing the forces acting on a sprinter and the surface.
2. **Guidelines**:
- Begin by identifying the objects involved: the sprinter and the surface.
- Focus on depicting all forces acting on these objects.
3. **Drawing Vectors**:
- Start each force vector at the designated black dots on the diagram.
- Ensure vectors are proportional to the magnitude of the forces they represent.
- Pay attention to the direction of each vector, which indicates the direction of the force.
4. **Considerations**:
- Common forces to include are gravitational force, normal force, frictional force, and applied force.
- Ensure the diagram clearly presents both interaction and balance of forces.
- Label each force appropriately to distinguish their effects.

Transcribed Image Text:**Transcription and Explanation:**
**Force Notations on the Left:**
- **\( \vec{n}_{sp \, on \, s} \)**
- Description: Normal force on the surface.
- **\( (\vec{f}_{s})_{sp \, on \, s} \)**
- Description: Static friction on the surface.
- **\( \vec{F}_{G} \)**
- Description: Gravity.
- **\( \vec{n}_{s \, on \, sp} \)**
- Description: Normal force on the sprinter.
- **\( (\vec{f}_{s} )_{s \, on \, sp} \)**
- Description: Static friction on sprinter.
**Image Description:**
- **Diagram of a Sprinter:**
- The image shows a sprinter running on a flat surface.
- There are two sets of axes depicted, one labeled "sprinter" and the other "surface."
- Each axis has an x and y component, suggesting a focus on the forces acting in these directions.
**Explanation of Diagram:**
The diagram illustrates the forces acting on a sprinter as they make contact with the ground.
- **Sprinter:**
- Represented by a point where the axes intersect, likely indicating the center of mass.
- Forces such as normal force and static friction may be acting on different axes.
- **Surface:**
- Also depicted with an x-y coordinate system to illustrate the interaction with the sprinter.
This setup is typical for analyzing the mechanics of motion, providing insight into the forces a sprinter must overcome as they accelerate. Understanding these forces is crucial for sports science and physics, allowing for optimization of performance and efficiency.
