resolving forces

• What is the purpose of using vector diagrams in this context?

  To resolve a single force into two components
• What type of students is this video intended for?

  Higher-tier students only
• What did the last video cover?

  Resultant of two forces acting at an angle
• What does resolving a force into two components mean?

  Breaking a force into horizontal and vertical parts
• What direction does a horizontal force act?

  In the horizontal direction
• What direction does a vertical force act?

  In the vertical direction
• What does a diagonal force indicate?

  It has both horizontal and vertical components
• What do the x and y-axes represent in a vector diagram?

  The horizontal and vertical components of a force
• What must the two components of a force be in relation to each other?

  They must be at right angles to each other
• How can you determine the magnitude of the components of a force?

  By drawing a vector diagram to scale
• At what angle is the 100 Newton force acting?

  35 degrees with the horizontal
• How long is the vector representing the 100 Newton force?

  10 centimeters
• What is the magnitude of the horizontal component in Newtons?

  83 Newtons
• What is the magnitude of the vertical component in Newtons?

  57 Newtons
• What should you do with faint lines in the exam?

  Blob out any faint lines used
• What is the question posed for the viewer to try?

  Resolve a 75 Newton force at 20 degrees
• What should you do after drawing the vector diagram for the viewer's question?

  Measure the lengths of the components
• What is the length of the horizontal component in the viewer's question?

  7 centimeters
• What is the magnitude of the horizontal component in the viewer's question?

  70 Newtons

• What are the steps to resolve a force into components using a vector diagram?

  1. Draw the force vector at the given angle.
  2. Draw horizontal and vertical axes.
  3. Draw dotted lines from the vector's head to the axes.
  4. Measure the lengths of the components.
  5. Convert lengths to magnitudes using the scale.
• What are the key components of resolving forces in physics?

  • Single force resolution into components
  • Use of vector diagrams
  • Right angles between components
  • Magnitude determination through measurement
