WebA number of problems can be caused by friction between two objects or materials. Since friction is a resistive force that slows down or prevents motion, it can be a nuisance, because it can hinder motion and cause the need for expending extra energy. Friction can also cause parts in contact to heat up and can cause parts in contact to wear out. little bad boy documentary about rizalWeb16 de nov. de 2024 · Method: Use the eraser to rub on the different surfaces mentioned above.
