I don't think equations are needed.

The equivalence principle is a fundamental concept in physics that states that the effects of gravity are indistinguishable from the effects of acceleration. This means that an observer in a uniform gravitational field cannot tell the difference between being at rest in that field and accelerating in the opposite direction with the same magnitude.
Helium balloons provide a good example of the equivalence principle because they experience an upward force due to the buoyant effect of air, which is similar to the force of acceleration due to gravity. This is because helium is less dense than air, causing it to rise and "float" in the air.
A helium balloon rises because of the difference in density between helium gas and the surrounding air. Helium is less dense than air, causing it to have a greater buoyant force and rise upwards. This is also known as Archimedes' principle.
Yes, the size of the helium balloon does affect its rising behavior. The larger the balloon, the more helium gas it can contain, resulting in a greater buoyant force. This means that a larger balloon will rise faster and higher than a smaller balloon of the same material.
The mass of the helium balloon does not affect its rising behavior significantly. This is because the buoyant force is determined by the difference in density between the balloon and the surrounding air, not the mass. However, a heavier balloon may require more helium gas to overcome its weight and rise, leading to a larger overall size and potentially affecting its behavior.
