• making surfaces rougher • push surfaces together with more force • move objects quickly
#3
Front (Question)
Decreasing friction
Back (Answer)
• makes surfaces smooth • reducing amount of surfaces in direct contact with each other • streamlining (travel through liquid - reduces drag) • using lubricants (oil, waxing)
#4
