Ravi hung four different weights on the same spring and measured the extension. Which graph correctly shows the relationship between the mass of the weight and the extension of the spring?

A A graph that starts at zero and goes down
B A graph where extension decreases as mass increases
C A graph where extension remains constant
D A graph where extension increases as mass increases

Worked Solution

Step 1: Elastic spring force is the force exerted by a stretched or compressed spring. Step 2: The more mass (weight) added, the greater the pulling force on the spring. Step 3: This results in a greater extension of the spring.

Correct answer: A graph where extension increases as mass increases
