Angela blows air into a balloon and holds the end of it closed with her fingers. When she lets go of the end of the balloon, Angela observes that the release of the air propels the balloon.  The propelling of the balloon from the release of the air is an example of which of Newton’s laws? 

• The force of an object is the product of its mass multiplied by its acceleration. 
•  A force of attraction exists between any two objects with mass. 
•  For every action, there is an equal and opposite reaction.
• An object in motion tends to stay in motion unless an unbalanced force acts upon it.
