The tendency of a body to oppose any change in its state of rest or of uniform motion is called:

  1. momentum
  2. inertia
  3. impulse
  4. acceleration
Show answer and solution

Correct answer: B. inertia

Inertia is a property associated with mass.

A quantitative measure of inertia of a body is its:

  1. mass
  2. volume
  3. weight
  4. density
Show answer and solution

Correct answer: A. mass

Greater mass ⇒ greater inertia.
