Percobaan Eksperimen Hukum Hook (Hooke's Law Experiment) | Praktikum Fisika Dasar 1

Summary

This video introduces a practical experiment on Hooke's Law, explaining the relationship between force and the extension of a spring. The experiment demonstrates how applying varying weights to a spring leads to proportional elongation, helping students understand the concept of spring constant (k). It also outlines the materials and steps required for the experiment, including the use of different springs, weights, and a stative. By measuring the elongation caused by different masses, students can calculate the spring constant and gain a deeper understanding of elasticity. The video concludes by encouraging students to carry out the experiment for hands-on learning.

Q & A

What is the objective of the experiment described in the script?

The objective of the experiment is to help students understand Hooke's Law and determine the spring constant (k) for different springs.

What is Hooke's Law?

Hooke's Law states that the force applied to a spring is directly proportional to the elongation (change in length) of the spring. This can be expressed as the formula F = k Δx, where F is the force, k is the spring constant, and Δx is the elongation.

What materials and equipment are used in the experiment?

The materials and equipment used in the experiment include two springs, varying masses (weights), a statif (stand), a holder, and an elastomer (spring).

What is the significance of the spring constant (k)?

The spring constant (k) represents the stiffness of a spring. A higher value of k means the spring is stiffer, and a lower value means it is more elastic or less stiff.

How is elasticity defined in the script?

Elasticity is defined as the ability of a material to return to its original shape after the applied force is removed or eliminated. An example of an elastic material is a spring.

How does the experiment measure the spring's elongation?

The elongation of the spring is measured by hanging different weights on the spring and recording how much the spring stretches in response to each weight.

What formula represents the relationship between force and elongation in Hooke's Law?

The formula that represents this relationship is F = k Δx, where F is the force applied to the spring, k is the spring constant, and Δx is the elongation or change in length of the spring.

What is the purpose of measuring different weights in the experiment?

The purpose of using different weights is to observe how the elongation of the spring changes with varying forces, which allows the calculation of the spring constant and demonstrates the proportionality described in Hooke's Law.

What role do the springs play in this experiment?

The springs serve as elastic materials that respond to the applied forces. By measuring the elongation of the springs when different weights are hung on them, students can explore how springs behave according to Hooke's Law.

What should students record during the experiment?

Students should record the initial length of the spring, the amount of elongation for each weight applied, and the results in a table for further analysis.
