Mass and weight differ in that:

  1. Mass depends on location, while weight is constant
  2. Mass and weight are always numerically equal
  3. Weight is a scalar and mass is a vector
  4. Mass is invariant, while weight depends on the local gravitational acceleration

Answer

D. Mass is invariant, while weight depends on the local gravitational acceleration

Solution

Mass is an intrinsic property of matter, while weight (W = mg) varies with the local value of gravitational acceleration.
