Yesterday we learned about friction. We learned that the force of friction acts on objects that rub together.
We know that when surfaces are rough there will be more friction. There will be less friction when the objects have smooth surfaces. In your comment, please tell me one thing that can be done to increase friction (make it rough or bumpy) and one thing to decrease friction (make it smooth). Remember to write your response in a full sentence! |
