4. Question Answer A-100 What quantity requires only magnitude? Give 2 examples of this quantity. Scalar – speed, mass, volume

5. Question Answer A-200 Your friend says that the heavyweight champion of the world cannot exert a force of 50 N on a piece of tissue paper with his best punch. The tissue paper is held in midair – no wall, no tricks. You: A) agree that it can't be done. B) have reservations about this assertion. C) disagree, for a good punch easily delivers this much force. A

6. Question Answer A-300 A bird sitting on the limb of a tree is moving about 30 km/s with respect to the sun. If the bird takes 1 second to drop down to a worm below, the worm would be 30 km downrange from the bird when it reached the ground. This faulty reasoning is best countered with Newton's Newton’s First Law

7. Question Answer A-400 Newton’s third law of motion states that, when one object exerts a force on a second object, the second object exerts a(n) _____ force in the________ direction. These two forces are called a(n) _______.When you push against an object, that push is called the ______ force. The force that the object exerts on you is called the _______force. Equal, opposite, force pair, action, reaction

8. Question Answer A-500 Find the value of the resultant vector 9cm (the other equation is for squares only!)

9. Question Answer What quantity requires both magnitude and direction? Give 2 examples. Vector – velocity, acceleration, force B-100

10. Question Answer B-200 The force exerted on the tires of a car to directly accelerate it along a road is exerted by the: Road

11. Question Answer B-300 An object ____________on Earth with just as much force as the Earth pulls downward on it. Pulls upward

12. Question Answer B-400 In the balloon rocket lab, what was the action force and what was the reaction force? Action= air leaving balloon Reaction=balloon moving

13. Question Answer B-500 A Mack truck and a Volkswagen traveling at the same speed have a head- on collision. The vehicle that undergoes the greatest change in velocity will be the Volkswagen

14. Question Answer C-100 What does Newton’s 3 rd Law state? For every action there is an equal and opposite reaction

15. Question Answer C-200 What make up force-pairs Action and reaction forces

16. Question Answer C-300 A player catches a ball. Consider the action force to be the impact of the ball against the player's glove. The reaction to this force is the Force the glove exerts on the ball

17. Question Answer C-400 State Newton’s First Law of Motion and the formula we used to find the distance of a free falling object. An object in motion stays in motion – d=1/2gt 2

18. Question Answer C-500 Since action and reaction forces are equal and opposite, why don’t they cancel to zero? because they influence the motion of different objects. The force that A exerts on B influences B's motion, and the force that B exerts on A influences A's motion.

19. Question Answer D-100 This quantity is represented with an arrow: Vector Quantities

20. Question Answer D-200 What should you do to get the sum of vectors going different directions? Subtract!

21. Question Answer D-300 What is the formula for acceleration and explain how acceleration is a scalar or vector component. a=v/t Vector because magnitude and direction

22. Question Answer D-400 A(n) ______________ to the system is needed for acceleration External Force

23. Question Answer D-500 When a pair of vectors are at right angles, is the resultant always greater in magnitude than either of the vectors separately? YES

24. Question Answer E-100 What are the sum of 2 or more vectors called? Resultant

25. Question Answer E-200 What should you do to get the sum of vectors going the same direction? Add them together!

26. Question Answer E-300 A automobile and a baby carriage traveling at the same speed collide head- on. The impact force is A) greater on the automobile. B) greater on the baby carriage. C) the same for both C

27. Question Answer E-400 Arnold Strongman and Suzie Small each pull very hard on opposite ends of a massless rope in a tug-of-war. The greater force on the rope is exerted by Both the same

28. Question Answer E-500 As a ball falls, the action force is the pull of Earth on the ball. The reaction force is the Pull of the ball’s mass on the Earth
