Newton's second law of motion states that the acceleration of a body is directly proportional to the force acting on the object and inversely proportional to the objects mass.
the more air (force) in a balloon the more the motion of the balloon. this relates to the Newton's first law
Newton's third law states that for every action there is an equal and opposite reaction:
the action of blowing up the balloon creates an equal and opposite reaction of the balloon flying away with an amount of speed proportional the force of the air blown into it
The frequency (f) in hertz (1/s) of the sound waves is the quotient when its speed (S) is divided by the wavelength (n). This is mathematically expressed,
