Which of the following statements is true?
A)The mass of a body is a quantitative measure of its inertia.
B)Mass is a vector quantity.
C)The mass of a body is directly proportional to the acceleration it is experiencing.
D)The unit of mass in the U.S.customary system is the newton.
E)The mass of a body is inversely proportional to the resultant force acting on it.

The first statement is true. Mass is a measure of the inertia of a body, which is the resistance of the body to changes in its state of motion. The greater the mass of a body, the greater its inertia, and the harder it is to change its motion. Mass is a scalar quantity, not a vector quantity. The mass of a body is not directly proportional to its acceleration, instead, it is inversely proportional to the acceleration. The unit of mass in the U.S. customary system is the slug, not the newton.
