Question
TRUE or FALSE to The force of friction can be difficult to deal with. Answer the following statements and justify your decision 4. a) Kinetic friction is generally less than static friction. Kinetic friction is always equal to the coefficient of kinetic friction times the normal force. b) Static friction is always equal to the coefficient of static friction times the normal force. c) d) Friction always slows down the speed of an object so it cannot accelerate an object e). Static friction cannot be a centripetal force because the object is in circular motion. 0. Static friction cannot accelerate an object because the object is in motion. g). Static friction can accelerate an object but Kinetic friction cannot because an object slides in the direction opposite to the motion.Explanation / Answer
a). False, static frictional force is greater than kinetic.
b). True. F= ukN
c). True.
d). True, frictional force Always opposes the motion, hence it always decrease the velocity.
e). False, Static friction can be equal to centripetal force.
f). False, static friction can't Accelerate object because it opposes the motion.
G). False, friction never accelerate object.
