Final answer:
The acceleration due to gravity of a falling object is 9.8 m/s².
Step-by-step explanation:
The acceleration due to gravity of a falling object is 9.8 m/s². This means that when an object is in free fall near Earth's surface, its velocity will increase by 9.8 meters per second every second. It is important to note that this value may vary slightly depending on the altitude and location on Earth, but for most practical purposes, it can be considered constant.
