Force Motion

• Sam ran for a long time, then slowed down to walk the rest of his trip. Once he got home, he sat down on the couch.

• Sam waited around after school for his friend, and then they ran home together.

• Sam walked for a while, stopped to sit on a bench in the park, and then ran the rest of the way home.

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

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.
