Which statement about mass and inertia is not true? A. Both mass and inertia play a role in Newton's first law.

B. Mass is a quantitative measurement of inertia.

C. The tendency of an object to remain at rest results from a property called inertia.

D. Newton's first law is sometimes called the relative inertia law.""

D. Newton's first law is sometimes called the relative inertia law.

Explanation:

Newton's first law of motion states that an object at rest will stay at rest and that in motion will stay in motion with same speed and in the same direction unless an unbalanced force acts on it. It is also called the law inertia. Mass and inertia play a role in this law because mass is a quantity that mainly depends on inertia in that a body with more inertial will exhibit more mass.

f=gm1m2/d^2 it d

f is force g is gravitaiton constant, m1 is mass of first object, m2 is mass of second object. d is distance between two object
