to cause an object to start moving on a frictional surface requires a. less force than is needed to keep it moving on the surface b. the same force as is needed to keep it moving on the surface c. more force than is needed to keep it moving on the surface d. a force equal to the weight of the object e. a force opposite to the normal force



Answer :

The answer is C. The force of Static friction(which is to cause something to move) is greater the force of kinetic friction(keeping an object in motion).
It is shown in the formula:
