Combining Forced (HT only)

• What is the concept of combining forces?

  Two forces acting on the same object
• What is the result of combining two forces?

  They form a single vector with the same effect
• How can two parallel forces be combined?

  By adding or subtracting their magnitudes
• What is needed if two forces are not parallel?

  A free body diagram is needed
• How are forces represented in this context?

  As arrows acting on the object
• What does the object represent in this scenario?

  A single point representing its center of mass
• Where does the resultant force arrow start?

  At the end of the first force arrow
• What does the resultant force represent?

  The combined effect of the acting forces
• What happens if F₁ is moved to the end of F₂?

  The resultant force can be calculated
• If F₂ is moved instead of F₁, what is the outcome?

  You end up at the same point
• What are the steps to combine two forces acting on the same object?

  • Identify the forces acting on the object
  • Determine if they are parallel or not
  • If parallel, add or subtract their magnitudes
  • If not parallel, draw a free body diagram
  • Calculate the resultant force based on the diagram
