1 The measure of the gravitational attraction between an object and the earth is defined as a weight b mass Newton d Normal force 2 A ball is tossed upward into the air Ignore air resistance What direction is the net force on the ball when it is in the air Upward b Downward c first upward then downward d first downward then upward 3 A book sits at rest on a table The table puts a force upward on the book According to Newton s Third Law a The earth puts an equal force downward on the book The earth puts an equal force upward on the table C The book puts an equal force downward on the table d The table puts an equal force downward on the earth 4 A bowling ball is raised a height above the surface of the earth and the separation of the ball and the earth stores 10 J of gravitational potential energy If an identical bowling ball is raised three times as high the amount of energy stored in the separation is a 30J 60 J c 90 J d 120 J 5 If a golf club applies a 2400 N force to a golf ball the ball applies 2400 N force to the club in the same direction b 2400 N force to the club in the opposite direction C a force less than 2400 N due to the lower mass of the ball d a force greater than 2400 N due to the higher mass of the club A particular spring stretches 2 5 cm when a mass of 200 g hangs on it If the 200 g mass is replaced with a 600 g mass the spring will stretch a 5 0 cm b 6 25 cm c 7 5 cm d 10 cm A block of mass M slides down a frictionless plane inclined at an angle 8 with the horizontal The gravitational force is directed toward the center of the Earth b perpendicular to the plane c parallel to the plane in the same direction as the movement of the block d parallel to the plane in the opposite direction as the movement of the block A box sitting on a horizontal surface is pulled by a 5 0 N horizontal force A 3 0 N friction force acts on the ox What is the net force acting on the object a ON b 2 N 5N d 8 N
