Q: The ........ of an object is fixed and does not change when it is moved -
  • A. Velocity
  • B. Mass
  • C. Speed
  • D. Weight
Correct Answer: Option B - The amount of matter in a body or object is called the mass of the object whereas the force with which the earth pulls the object towards itself is called the weight of that object. The mass is always fixed and unchanging while the weight is variable depending on the gravitational acceleration. The mass remains unchanged when the object is moved to any place.
