The air resistance pushing upwards on the apple as it falls. B. The apple pulling on the Earth in the upward direction. C. There is no reaction force; the Earth is far too big for the apple to exert a force on the Earth. D. The acceleration of the apple (downwards) is the reaction. E. The apple pushing its way through the air as it falls. C - correct answer One difference between mass and weight is that A. weight is a constant value at any/all locations B. mass tells us how much space an object occupies; weight tells us the gravitational force. C. weight is measured with a spring scale, mass is measured on a balance. D. weight is the force an object has a rest. Mass only matters in acceleration problems. E. There is no difference. Mass and weight are really the same thing. C - correct answer An object is moving and accelerating to the right because of a net force of 50 N.

C. continues traveling to the right at a constant speed. D. accelerates at a greater speed to the right. E. will move in a way that can't be determined from the information given. B - correct answer The normal force could be defined as A. the opposite of the abnormal force. B. a perpendicular to the surface force between an object and the surface on which it sits. C. the opposite of the weight of an object. D. the force that holds an object down on a surface. E. a frictional force. F. something not specified here. E - correct answer An object is observed to be moving at a constant velocity. Which of the following statements is always true? A. No force must be acting on the object. B.
