Learning Outcomes

• Identify the forces acting on an object.
  • • Recognize when each of the following forces act on an object:
      • a gravitational force due to an object’s interaction with the Earth’s gravitational field
      • normal and friction components of a contact force due to the object being in contact with a surface
      • a tension force due to the object being pulled by a rope, string, cable, etc.
      • an applied force due to the object being pushed by something else
    • For a particular force, identify the following:
      • the two objects interacting to generate the force,
      • which object the force is exerted on, and
      • which object the force is exerted by.
