• more

When a bird flies, its wings push air downward. As a result the air pushes back upward on the bird. Which law of motion most applies to the way the wings of a bird beat? 

• Every action has an equal and opposite reaction
• The rate of acceleration of an object depends on the amount of force applied.
• Objects in motion tend to remain in motion until acted upon by an another force. 
• Force is defined by mass times acceleration

A change in distance in a certain time is

• Speed
• position
• acceleration
• force
