For a freely falling body, its acceleration ________as it falls.

Explanation

To solve the question "For a freely falling body, its acceleration ________ as it falls," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Free Fall**: A freely falling body is one that is only influenced by the force of gravity, with no other forces acting on it (like air resistance).

2. **Identifying the Force**: The only force acting on the body during free fall is the gravitational force (Fg). This force can be expressed using Newton's law of universal gravitation:
