Question

which of the following is/are true?
i. mass is a vector quantity.
ii. mass is a scalar quantity.
iii. mass is a measure of how much matter an object contains.
iv. there is no relationship between force and mass.
v. isaac newton developed three important laws of motion that describe the relationship between force and mass.
o ii, iv, and v only
o ii, iii, and v only
o i and iii only
o ii, iii, and iv only
o ii and iii only

Explanation:

• Mass has only magnitude and no direction, so it's a scalar quantity, not a vector (II is true, I is false).
• By definition, mass measures the amount of matter in an object (III is true).
• Force and mass are related by Newton's second - law ($F = ma$), so IV is false.
• Newton's three laws of motion describe relationships between force, mass, and motion (V is true).

Answer:

II, III, and V only
