A student places a marble at the top of a ramp, as shown. Halfway down the ramp, the student places a piece of cardboard in the path of the marble. How will the motion of the marble be affected by the piece of cardboard, and why?
The marble will remain on its path because of balanced forces.
The marble will remain on its path because of unbalanced forces.
The marble will change direction because of unbalanced forces.
The marble will change direction because of balanced forces.
