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

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
