Basic Questions On Friction! Trivia Quiz
(148).jpg "Basic Questions On Friction! Trivia Quiz - Quiz")
Friction is the force opposing the relative motion of solid surfaces, fluid layers, and material elements coming against each other. This quiz features questions concerning friction. You should be aware of what type of force is friction, which direction does friction act, is there friction when two objects are not in contact, is static friction larger than dynamic friction, and when friction is most experienced. Don’t let this quiz rub you the wrong way; you will ACE it.
