Action: Object A exerts a force on object B. 

Reaction:

Reaction: Object B exerts a force on object A.

A given force exerted on a small mass produces a _________ acceleration than the same force exerted on a large mass.

greater

True/False: When a net force is exerted on a system, the system will accelerate, but when an applied force and its reaction are within a system, the system as a whole does not accelerate. 

TRUE

When you rub your hands together, can you push harder on one hand than the other. 

No, each hand pushes equally on the other. 

200

True/False: Action force occurs first and the reaction force occurs second. 

FALSE! They Occur at the same time.

If a bat hits a baseball with 1,000 Newton's of force, what force does the baseball hit the bat?

Also 1,000 Newtons
200

Define the relationship between acceleration and force AND mass. 

Directly proportional to force and inversely proportional to mass. 

200

When can two kicks on a soccer ball produce a net force of zero on the ball?

When both kicks are simultaneous, equal magnitude, and opposite direction. 

200

Your weight is the result of the gravitational force of Earth on your body. What is the corresponding reaction force?

Your body pulling on Earth.

300

When you walk on a floor, what allows you to move forward. Be specific. 

The frictional force of the ground on your feet. 

300

Which force is greater, the earth pulling on the moon or the moon pulling on the earth?

Neither, the force is the same!

300

If the world pulls you downward against your chair, what is the reaction force? 

The reaction is you pulling up on the world.

300

Why don't the enormous number of interatomic forces inside a baseball accelerate the baseball. 

They act WITHIN the system, so there is no net force ON the system.

Why can you exert greater force on the pedals of the bicycle if you pull up on the handlebars?

It pushes your body down into the pedals thus producing more force.

State Newton's Third Law. (full version)

Newton’s third law states that whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object.

Identify the force the propels a rocket? Be specific.

Exhaust gases push up on the rocket as the rocket pushes the exhaust gases downwards.
