Give 2 examples of this quantity. • Scalar – speed, mass, volume Answer Question 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 Answer Question 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 Answer Question 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 Answer Question A-500 • Find the value of the resultant vector • 9cm (the other equation is for squares only!) Answer Question B-100 • What quantity requires both magnitude and direction? Give 2 examples. • Vector – velocity, acceleration, force Answer Question B-200 • The force exerted on the tires of a car to directly accelerate it along a road is exerted by the: • Road Answer Question B-300 • An object ____________on Earth with just as much force as the Earth pulls downward on it. • Pulls upward Answer Question 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 Answer Question B-500 • A Mack truck and a Volkswagen traveling at the same speed have a headon collision. The vehicle that undergoes the greatest change in velocity will be the • Volkswagen Answer Question C-100 • What does Newton’s 3rd Law state? • For every action there is an equal and opposite reaction Answer Question C-200 • What make up force-pairs • Action and reaction forces Answer Question 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 Answer Question 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=1/2gt2 Answer Question 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. Answer Question D-100 • This quantity is represented with an arrow: • Vector Quantities Answer Question D-200 • What should you do to get the sum of vectors going different directions? • Subtract! Answer Question 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 Answer Question D-400 • A(n) ______________ to the system is needed for acceleration • External Force Answer Question 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 Answer Question E-100 • What are the sum of 2 or more vectors called? • Resultant Answer Question E-200 • What should you do to get the sum of vectors going the same direction? • Add them together! Answer Question E-300 • A automobile and a baby carriage traveling at the same speed collide headon. The impact force is A) greater on the automobile. B) greater on the baby carriage. C) the same for both • C Answer Question 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 Answer Question 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 Answer Question FINAL JEOPARDY • ANSWER: • QUESTION: Answer Question
