Which of the following statements is correct about friction?Group of answer choicesFriction always acts in the opposite direction to the direction of motion of an objectFriction is measured in kilogramsFriction always acts in the opposite direction to the direction of motion of an objectFriction always acts on stationary objects

Which of the following statements in incorrect about friction?Group of answer choicescoefficient of kinetic friction depends on the speed of motioncoefficient of kinetic friction depends on the normal force on the objectcoefficient of kinetic friction depends on acceleration of the objectcoefficient of kinetic friction does not depend on the direction of motioncoefficient of kinetic friction depends on the direction of motion

Friction is a force that ALWAYS acts:a) In the direction of motionb) Opposite the direction of motionc) Perpendicular to the surfaces in contactd) It depends on the materials in contact

An object is moving with a constant positive velocity along positive horizontal x-axis. Which of the following statement is true?Group of answer choicesnet force on the object is non-zero in the negative direction of xthe net force on the object is equal and opposite to the kinetic friction force on the objectthe net force on the object is equal and opposite to the maximum static friction force on the object.the object must be moving on a frictionless surfacethe net force must be equal to the normal force on the object

Newton's second law of motion states that when a net force acts on an object the object will __________ in the direction of the force. Group of answer choicesbalancepush backacceleratecome to rest
