 kinetic friction always poopses the motion of an object. true a block rests on a 60 degree plane. the normal force that the plane exerts on the block is mgcos60 if a car turns a corner too quickly you seem to be thrown against the door because of inertia a large truck and a small car have a head on collision, which will experience the greastes impact force? the same for both an object expereinces no acceleration. which of the following cannot be true for the object? a single force acts on the object. which of the following is the reaction force to the gravitational force acting on your body as you sit in your desk chair? the normal force from the chair. the force of static friction always equals UsN true if we known an object is moving at constant velocity, we may assume: the net force is zero an object moving at constant speed in a circular path has acceleration directed to the center of the circle the max value of static friction is usually ___ kinetic friction. grater than Authortay ID122840 Card Setphysics 7 Descriptionphysics 7 Updated2011-12-12T00:21:16Z Show Answers
