Questions and Answers

What is the primary difference between mass and weight?

  • Mass is the force of gravity, while weight is the amount of matter in an object
  • Mass is the acceleration of gravity, while weight is the force that resists motion
  • Mass is the force that increases the velocity of falling objects, while weight is the acceleration of gravity
  • Mass is the amount of matter in an object, while weight is the force of gravity acting on the object (correct)
  • What is the acceleration of gravity on Earth?

  • 11.0 m/sec2
  • 9.5 m/sec2
  • 9.8 m/sec2 (correct)
  • 10.0 m/sec2
  • What is the relationship between the mass of objects and the amount of gravity between them?

  • The amount of gravity is unrelated to the mass of the objects
  • The amount of gravity is directly proportional to the mass of the objects (correct)
  • The amount of gravity is inversely proportional to the mass of the objects
  • The amount of gravity is proportional to the square of the mass of the objects
  • What is the force that increases the velocity of falling objects?
