# Would it be correct to say that inertia is the reason a moving object continues in motion when no force exists?

I think that is correct. Inertia is the property that allows an object to continue moving in the same direction and at the same velocity unless acted upon by a force. I think your statement follows from that. Inertia ALSO is the property that allows an object at rest to remain at rest unless acted upon by some force.

## Yes, you are correct. Inertia is indeed the reason why a moving object continues in motion when no external force is acting upon it. This principle is stated in Newton's first law of motion, also known as the law of inertia. According to this law, an object at rest will remain at rest, and an object in motion will continue moving in a straight line at a constant speed, unless acted upon by an external force.

To understand why this happens, we need to consider the concept of inertia. Inertia is the tendency of an object to resist changes in its state of motion. An object at rest has a natural tendency to remain at rest due to its inertia, and an object in motion tends to keep moving in the same direction and at the same speed due to its inertia.

In the absence of any external force, there are no influences that can change the state of motion of the object. Therefore, the object's inertia allows it to continue moving with the same velocity indefinitely.

Overall, your statement correctly identifies inertia as the reason why a moving object continues in motion when no force exists.
