Safiya is standing in a room with a helium-filled balloon tied to her wrist. If Safiya suddenly jumps up, what happens to the balloon? Provide a very brief response.
When Safiya jumps up, she moves closer to the balloon because she is moving upwards and the distance between her hand and the balloon decreases. The balloon, however, will not move significantly with her jump. Since the balloon is buoyant and filled with helium, it is already floating and will largely stay in place, offsetting the gravitational pull because the helium is less dense than air. As Safiya moves upward, the string may pull slightly on the balloon, but once she stops ascending and starts to fall back down due to gravity, the balloon will return to its original position above her.
