Question 4 (1 point) which force is always perpendicular (90 degree angle) to a surface. so, if you are sitting on the floor, what is the name of the force "the floor pushes up on you"? question 4 options: normal tension friction weight question 5 (1 point) which free body diagram is in equilibrium? question 5 options: a b both a and b. neither a nor b. question 8 (1 point) name the applied force in the free body diagram: question 8 options: the table pushes up on the block the spring scale drags the box gravity pulls the block down the dotted line pointing opposite the direction of the motion question 9 (1 point) the airplane is flying with a constant velocity. which force acting on the airplane below represents the friction from air resistance? question 9 options: a b c d question 11 (1 point) andrew is pushing this block to the right across on the floor. which force in the free body diagram is pointing in the wrong direction? question 11 options: the weight friction the normal force the applied force question 12 (1 point) which of these statements is always true? question 12 options: a moving object in equilibrium can change its direction but not its speed. if an object is moving, a net force is acting on it. a moving object in equilibrium continues at a constant velocity. an object in equilibrium must not be in motion.
