• What can a number of forces acting on an object be replaced by?

  A single force with the same effect
• What is the resultant force?

  It is the single force representing multiple forces
• What happens if all forces acting can cancel out?

  There is zero resultant force
• What does zero resultant force indicate about an object?

  The object is in equilibrium
• What are the implications of having a resultant force of zero?

  • The object is in equilibrium
  • No net force acting on the object
  • The object remains at rest or in uniform motion
