Describe How Inertia Affects Motion. Inertia is the resistance an object has in its state of motion. However the term mass is not only used to quantify inertia but also to quantify other physical properties of a substance as well.

For example if you roll a ball it will continue rolling unless friction or something else stops it by force. We see examples of inertia. If the item is moving inertia will keep moving.
If an object is already at rest inertia will keep it at rest.
