Question

In physical science class Jonathan says that inertia is a property of all objects with mass and velocity. Which of the following statements would be a correct response to Jonathan?

A. Objects with mass and velocity do not have inertia.
B. Some objects with mass and velocity have inertia while some do not.
C. All objects with mass have inertia, even if they do not have velocity.
D. Objects do not need to have mass to have inertia, but they must have velocity.

Answer 1

Inertia is what matter possesses that causes it to keep away from any change in its state of motion. All objects possess a given velocity and that velocity is maintained unless an external force acted upon it. Therefore, all objects with mass possess inertia even if they do not possess velocity. Answer on this is option C.
