In a free-body diagram, what does the length of a force vector represent?
The magnitude of the force.
In a free-body diagram, what does the direction of a force vector represent?
The direction in which the force is acting.
What are the steps to draw a Free-Body Diagram?
- Isolate the object. 2. Sketch the object. 3. Identify forces acting on the object. 4. Draw force vectors. 5. Label forces. 6. Add a coordinate system (if needed).
How do you apply Newton's Second Law to solve a problem?
- Draw a free-body diagram. 2. Resolve forces into components. 3. Apply in each direction. 4. Solve for the unknown.
What is the first step in solving force problems using free-body diagrams?
Isolate the object of interest by focusing on one object at a time.
What should you do after identifying all the forces acting on an object?
Draw force vectors with arrows representing each force, starting from the object.
What is the final step in creating a free-body diagram?
Add x and y axes if needed for analysis to create a coordinate system.
What are the steps to draw a Free-Body Diagram?
- Identify the object. 2. Sketch the object. 3. Identify forces (Gravity, Normal Force, Tension, Friction, Applied Force). 4. Draw force vectors. 5. Label forces. 6. Add coordinate system (if needed).
