Standard Science Primary 6 Interactions

Ravi conducted an experiment to find out how the type of surface affects the amount of force needed to pull a 500g wooden block. The results are shown in the table below. <br><br>Which surface has the GREATEST amount of friction?

A Surface Z
B Surface W
C Surface X
D Surface Y
Show Worked Solution

Worked Solution

Step 1: Identify that friction is the force that opposes the motion of the block. Step [2-9]: A higher pulling force is required to overcome a higher frictional force. Step [2-9]: Compare the forces: Surface Y requires 4.2N, which is the highest value in the table. Final Answer: Surface Y.

Correct answer: Surface Y
