Step 1: Identify the correct definition of mass and weight.
Mass is a measure of the amount of matter in an object. It is a fundamental property of an object, unaffected by external factors such as gravity or location. Mass is typically measured in kilograms (kg) or slugs. Weight, on the other hand, is a force acting on an object due to gravity. It depends on the mass of the object and the acceleration due to gravity. Weight is typically measured in newtons (N) or pounds-force (lbf).
Step 2: Analyze the given answer choices.
A. Mass includes acceleration due to gravity. (Incorrect, as mass does not depend on gravity.) B. Mass and weight are the same things. (Incorrect, as mass and weight are different physical quantities.) C. Weight includes acceleration due to gravity. (Correct, as weight is a force caused by gravity acting on an object's mass.) D. Mass and weight are the same but have different units. (Incorrect, as mass and weight are different physical quantities with different units.)
Final Answer
The correct answer is C: Weight includes acceleration due to gravity.
