What type of friction opposes the initiation of motion between two dry stationary surfaces in contact?
Answer and explanation
Correct answer: C. Static friction
- Step 1: Static friction is the frictional force that must be overcome to start moving a stationary object. Step 2. It is always greater than the kinetic friction experienced once motion is established. Answer: Static friction. Why not the others: Kinetic friction acts during sliding motion; rolling friction acts on wheels/balls; fluid friction acts in liquids and gases.
