Standard Science Primary 6 Interactions

Two identical springs, P and Q, are hung from a ceiling. A 100g weight is hung on Spring P and a 200g weight is hung on Spring Q. Which of the following is correct?

A Spring P will have a greater extension than Spring Q.
B Spring Q will have a greater extension than Spring P.
C Both springs will have the same length.
D Spring P will exert more elastic spring force than Spring Q.

Worked Solution

Step 1: Elastic spring force depends on the extension of the spring. Step 2: A heavier load (200g) exerts more pulling force on the spring than a lighter load (100g). Step 3: Therefore, Spring Q will stretch further (greater extension).

Correct answer: Spring Q will have a greater extension than Spring P.
