Question 14(multiple choice worth 4 points) (01.02 mc)

two descriptions about physical quantities are given below:

quantity a: it remains constant.

quantity b: it depends on gravitational pull.

what quantities are these most likely describing?

both quantity a and quantity b are mass.

both quantity a and quantity b are weight.

quantity a is weight and quantity b is mass.

quantity a is mass and quantity b is weight.

Option D

Quantity A is mass and Quantity B is weight.

Explanation:

Mass of the body is the amount of matter in that body. The amount of matter remains the same regardless of the position or location of the body. Mass is also not affected by gravitational pull. Thus mass remains constant everywhere. Mass of the body will be the same on Earth and on Moon.

Hence Quantity A represents mass

Weight of the body is totally dependent on the gravitational pull. Infact, weight is calculated as mass times gravitational acceleration (g) i.e.

w = mg

Weight will vary at different positions. Weight of a body on Earth will be different than its weight on moon because the gravitational pull of Earth and Moon is different.

Hence Quantity B represents weight.
