Standard Science Primary 6 Interactions

Siti wanted to find out how the type of surface affects the distance a toy car travels. She released the car from the top of a ramp on four different surfaces and recorded the results. Which surface likely had the HIGHEST friction?

A Surface D: 155 cm
B Surface C: 40 cm
C Surface A: 120 cm
D Surface B: 85 cm

Worked Solution

Step 1: Friction is a force that opposes motion between two surfaces. Step 2: Higher friction results in more resistance, causing the car to stop sooner and travel a shorter distance. Step 3: Surface C has the shortest distance (40 cm), meaning it has the highest friction.

Correct answer: Surface C: 40 cm
