Siti pushed a wooden block across four different surfaces with the same amount of force. The distance moved by the block was recorded. On which surface was the frictional force the GREATEST?
Show Worked Solution
Worked Solution
Step 1: Frictional force opposes motion.
Step 2: Greater friction results in a shorter distance moved before the block stops.
Step 3: Comparing the distances, 10 cm is the shortest distance.
Step 4: Therefore, the surface where the block moved 10 cm has the greatest friction.
Correct answer: Surface with distance 10 cm
