Standard Science Primary 6 Interactions

Siti pushed a wooden box across a tiled floor and then across a carpeted floor using the same amount of force. She found that the box moved a shorter distance on the carpet. Which of the following best explains this?

A The carpeted floor exerted more frictional force on the box.
B The carpeted floor is smoother than the tiled floor.
C The box has more mass when it is on the carpet.
D There is more gravitational force acting on the box on the carpet.

Worked Solution

Step 1: Identify that the box moved a shorter distance, meaning it was slowed down more. Step 2: Friction is a force that opposes motion and depends on surface roughness. Step 3: Carpet is rougher than tiles, providing more frictional force. Step 4: Final Answer: The carpeted floor exerted more frictional force.

Correct answer: The carpeted floor exerted more frictional force on the box.
