You are presented with the quiz "Applying a force in the same direction an object is moving will cause what?" 

But you don't know the answer, so you turn to your teacher to ask for hints. He says that "force causes the speed of an object to increase" and "kinetic energy varies as the square of the speed of a moving body". 

So, what's the best answer to the question?


 

        Increase in kinetic energy
