If Xiomara stands on a cliff's edge and holds a balloon on a string in one hand while her friend Leandro stands on the ground below her but several steps back from the cliff base, what would Leandro see if she releases the balloon?
Provide a very brief response.
Leandro would see the balloon float upward from Xiomara's hand if it is filled with a lighter-than-air gas like helium. Since the balloon tends to rise due to being less dense than the surrounding air, gravity would not pull it directly down towards Leandro's position on the ground. Instead, if there is no wind, Leandro would watch the balloon ascend vertically above Xiomara. If there is a breeze, the balloon might drift in the direction of the wind as it rises.
