Question

if a block is already put in motion, which of the following statements apply? the force needed to overcome the sliding friction is less than the force needed to overcome the starting friction. the force needed to overcome the sliding friction is equal to the force needed to overcome starting friction. the force needed to overcome the sliding friction is greater than the force needed to overcome the starting friction. no force is needed to overcome sliding friction once force has been applied to overcome the starting friction.

Answer 1

Answer: Choice A. The force needed to overcome the sliding friction is less than the force needed to overcome the starting friction.

Step-by-step explanation:

This is correct, I just had this question and this was the right answer :)

Answer 2

no force is needed to overcome sliding friction once force has been applied to overcome the starting friction.
