It is enough not to exist the attrition force. d) A body alone remains in movement if to exist the attrition force acting on it. 02) Definitive data body in rest, we can affirm that: ) No force does not exist acting on this body. b) The addition of the forces that acts in the body is different of zero c) Only exists an only force acting on this body. d) The addition of the forces that acts in this body is zero.
03) One determined body is in free fall, disdaining the resistance of air.

He designates the correct alternative regarding this phrase: ) This affirmation is correct, it says therefore it of the personage well was translated of the English. b) This affirmation is correct, because the force is resultant of the action of the Man. c) This affirmation is missed, therefore the Man does not have force and nor applies force, it he is resulted of the interaction between the bodies, and alone he appears while the bodies are interacting.
d) This affirmation is missed, therefore the force is the result of the interaction between the bodies, and alone it appears while the bodies are interacting. Then, He Man would have to say. ‘ ‘ I am capable To apply the great force of intensidade’ ‘. 05) He draws the forces that act in a rock when it is launched for top and when it is launched for low, considering the resistance of worthless air.
