Question
Chapter 7A, Problem 1PLA
To determine
Whether the statement is true or false.
Expert Solution & Answer
Answer to Problem 1PLA
Option (a) True
Explanation of Solution
Kinetic friction is the force that acts between moving surfaces that are in mutual interaction with each other. This force always acts in the direction opposite to the motion of the object on the surface.
Therefore, the given statement is true.
Conclusion:
Option (a) is correct. For kinetic friction the direction of the frictional force on a given object is always opposite the direction of that object’s motion.
