Question

the inertia of an object is related to its:
a. mass and force.
b. mass and speed.
c. mass only.
d. speed only.

Explanation:

Inertia is a property of matter. According to Newton's first law, the inertia of an object depends solely on its mass. Mass is a measure of the amount of matter in an object. The greater the mass of an object, the greater its inertia. Force and speed do not determine inertia. Force can change the motion of an object (Newton's second law \(F = ma\)), but it is not related to the inherent property of inertia. Speed is a measure of how fast an object is moving and is not a determinant of inertia.

Answer:

C. mass only.
