Hooke’s Law Experiment

Hooke’s Law: Force (Newton) = force constant * extension of the spring (Cm)

Aim: The purpose of this experiment is to test and verify that Hooke’s law is correct, which is the extension of a spring is in direct proportion with the load added to It as long as this load does not exceed the elastic limit.

Hypothesis: The weight of the object is directly proportional to the extension of the spring.

Independent variable: The weight of the object.

Dependent variable: Spring’s extension.

Controlled variable: Use the same spring for the experiment, and choose objects that have the same shape but different mass. Also make sure that the spring stays in the same height from the ground.

Materials: Round shaped object which different mass, Ruler, Spring, and Stand.

Procedure: First, the experiment starts by using a stand with the spring attach on it 30 cm from the table. Then, use a ruler to measure the spring from the very begging to the end and record the starting length. Later, attach a round-shaped object which is 50 grams on the end of the spring, and use a ruler to measure the current length. Repeat the experiment and add 50 grams more each time.
