PROBLEM TO BE SOLVED: To provide a method, an apparatus and a program for measuring a difference in acting force for correctly evaluating, for example, a difference in frictional resistance depending on a type of a coating film in the water, a difference in frictional resistance of different surface states or the like as a minute difference by using two objects with a very small difference in acting force when activated. SOLUTION: The apparatus accurately measures a difference in resistance by measuring the resistance of two testing plates placed in parallel, moment between the testing plates and resistance force. In concrete, the method for measuring the difference in resistance force is characterized by that it includes steps of driving the two objects under test simultaneously under the same conditions, measuring a change including the moment and/or resistance force occurring on the two objects, and evaluating at least the difference in the resistance force.
