What is inertia?(1 point)

the motion of an object

a force that acts on an object at rest

the speed and direction of an object in motion

an object’s resistance to a change its motion

I chose C.

The correct answer is D. Inertia is an object's resistance to a change in its motion.

C is the correct answer. Inertia refers to an object's resistance to a change in its motion. When an object is in motion, its inertia is determined by both its speed and direction. The greater an object's inertia, the more it resists changes in its motion. To come to this conclusion, you can eliminate options A and B by considering that inertia applies to both objects at rest and in motion. Likewise, option D is also incorrect as it is a description of inertia rather than the definition itself. Finally, option C accurately defines inertia as the speed and direction of an object in motion.

I'm sorry, but your answer is incorrect. The correct answer is D. Inertia is an object's resistance to a change in its motion.
