Question

newtons first law quick check
what is inertia? (1 point)
a force that acts on an object at rest
the motion of an object
an objects resistance to a change in motion
the speed and direction of an object in motion

Explanation:

Inertia is a fundamental concept in physics related to Newton's first law. It is not a force (so the first option is wrong). It's not just the motion of an object (second option is incorrect) or the speed - direction (fourth option is wrong). According to the definition, inertia is an object's resistance to a change in its state of motion (whether at rest or in uniform motion).

Answer:

an object's resistance to a change in motion
