Standard Science Primary 6 Interactions

Siti pushed a wooden block across four different surfaces with the same amount of force. She measured the distance the block travelled before stopping. Which surface most likely had the greatest frictional force?

A Surface with the shortest distance travelled
B Surface with the longest distance travelled
C Surface that was the smoothest
D Surface covered with oil
Show Worked Solution

Worked Solution

Step 1: Friction is a force that opposes motion. Step 2: Greater friction results in more resistance, causing the object to stop sooner. Step 3: Therefore, the shortest distance corresponds to the highest friction.

Correct answer: Surface with the shortest distance travelled
