A gas filled balloon moves up. Is the upward force acting on it larger or smaller than the force of gravity?

Explanation

To determine whether the upward force acting on a gas-filled balloon is larger or smaller than the force of gravity when the balloon moves up, we can analyze the forces involved.

### Step-by-Step Solution:

1. **Identify the Forces Acting on the Balloon**:
- There are two main forces acting on the balloon: the upward force (buoyant force) and the downward force (force of gravity).

2. **Understand the Direction of Movement**:
