Study Notes

Gravitational Forces and Fields

  • An object dropped between Earth and the moon would fall in the direction of the moon's center. True
  • Force fields can be used to predict the strength and direction of non-contact forces. True
  • The gravitational field arrows represent the direction of the force, not the actual force on an object. False
  • The spacing of the arrows in the gravitational field represents the strength of the forces. True
  • A force field is a model that describes the force on an object if it were placed in any location in space. True
  • Gravitational fields are maps of force fields that predict the direction of gravitational forces on objects. True

Key Concepts and Definitions

  • Force field: a model that describes the force on an object if it were placed in any location in space
  • Gravitational field: a map of force fields that predict the direction of gravitational forces on objects
  • Non-contact forces: forces that act on objects without physical contact, such as gravity

Everyday vs. Scientific Meanings

  • Gravity: everyday meaning - a downward pull; scientific meaning - a force that attracts objects with mass towards each other
