Question

cca 2 retest
this diagram represents a balloon that is moving in one direction while escaping air is moving in the opposite direction.
what causes the balloon to move?
a action - reaction forces
b gravitational potential energy
c electrical forces
d friction

Explanation:

When air escapes from the balloon in one direction, according to Newton's third - law of motion, there is an equal and opposite reaction force that propels the balloon in the opposite direction. Gravitational potential energy is related to height and mass and is not the cause here. Electrical forces are related to charged particles and not relevant. Friction opposes motion and is not the driving force for the balloon's movement.

Answer:

A. action - reaction forces
