What would most likely happen to the motion of the box if you poured oil on the ramp?

• It will slow the box because the force of friction will be increased.

• It will speed up the box because the force of friction will be increased.

• It will slow the box because the force of friction will be reduced.

• It will speed up the box because the force of friction will be reduced.
