Advanced Science Primary 6 Interactions

Ravi conducted an experiment to compare the friction of different materials. He measured the force needed to start pulling a block across each surface. Which surface has the MOST friction?

A Surface W (Force: 5N)
B Surface Y (Force: 8N)
C Surface Z (Force: 3N)
D Surface X (Force: 12N)
Show Worked Solution

Worked Solution

Step 1: Friction opposes the start of motion. Step 2: A higher force required to move the block indicates a higher frictional force to overcome. Step 3: Surface X requires 12N, which is the highest value in the list. Final Answer: Surface X (Force: 12N)

Correct answer: Surface X (Force: 12N)
