If Leila stands on a hilltop holding a balloon with a string and the wind is blowing from her left to her right, in what direction will the balloon move? Provide a very brief response.
The balloon will move to the right from Leila's perspective. Wind blowing from left to right will exert a force on the surface of the balloon, causing it to be pushed along the direction of the wind. The balloon, being lighter than air and subject to less inertia than heavier objects, will react quite responsively to the wind's force, hence it will be seen moving to the right side. The string will tilt in the direction of the wind as Leila continues to hold it, indicating the wind's direction and strength visually.
