Equilibrium Forces

• What happens if all the force arrows acting on an object cancel out?

  There is no resultant force
• What does it mean for an object to be in equilibrium?

  The object experiences no resultant force
• How can you test if an object is in equilibrium?

  Move the force arrows so they align
• What must happen to the force arrows for an object to be in equilibrium?

  They must be one after the other
• What does it indicate if the shape formed by the force arrows is closed?

  The object is in equilibrium
• What is the significance of the three vectors forming a closed shape?

  It confirms the object is in equilibrium
• What are the conditions for an object to be in equilibrium?

  • All force arrows must cancel out
  • The shape formed by the force arrows must be closed
