Draw a free body diagram of the forces acting on the helium balloon in three different scenarios. Label the forces and write the values of the gravitational force, the buoyant force (lift), and the net force. Scenario 1: Helium balloon lifting off the ground Scenario 2: Helium balloon hovering midairScenario 3: Helium balloon landing
While the procedure aimed to achieve equilibrium to make the balloon stay still in one spot, it could still move side to side because of things like wind, turbulence, not being perfectly balanced, and changes in the weather.
4. In the equilibrium position, what is the net force acting on the balloon? Explain why. written like a 8th grader
Scenario 1: Helium balloon lifting off the ground
- Gravitational force (downward)
- Buoyant force (lift) (upward)
- Net force = Buoyant force - Gravitational force
- Value of forces depends on the mass of the balloon and the volume of helium inside.
Scenario 2: Helium balloon hovering midair
- Gravitational force (downward)
- Buoyant force (upward)
- Net force = 0 because the balloon is not accelerating in any direction.
Scenario 3: Helium balloon landing
- Gravitational force (downward)
- Buoyant force (upward)
- Net force = Gravitational force - Buoyant force
4. In the equilibrium position, the net force acting on the balloon is 0 because the forces are balanced. This means that the balloon is not moving in any direction.
