Answer:

When a balloon is inflated, the pressure inside the ballon is greater than the pressure outside the balloon. When let go of (or when the balloon is open), the air is released as there is no long a difference in pressure between outside the balloon and inside the balloon. This results in a force in the opposite direction due to the escaping air that provides the force, which causes it to fly away!

Hope this helps :)

What causes the ballon to fly away is the air pushing out of the balloon also tied in with air pressure

Consider Newton's Law of Universal Gravitation: FG= G (m1 m2)/d2 .

Answer:

Mass is directly proportional to the Force of Gravity. If Mass increases, then the Force of Gravity increases; however, Distance is indirectly (or inversely) proportional to the Force of Gravity. If Distance increases, then the Force of Gravity decreases.

Explanation:

The formula for the force of gravity between two objects is

$F=G\frac{m_1 m_2}{d^2}$

where

G is the gravitational constant

m1, m2 are the masses of the two objects

d is the separation between the two objects

We notice the following:

- F is directly proportional to the masses, $F\propto m_1, m_2$ . This means that if one of the masses increases, then the force between them, F, increases in a proportional way

- F is inversely proportional to the square of the distance, $F\propto \frac{1}{d^2}$ . This means that if the distance between the two objects is increased, the force between them will decrease, and vice-versa.
