Nowadays, many people like to do extreme activities such as bungee jumping to challenge themselves to fight with their fear feeling. Some people hold their desire to do it because of their fear of the materials used was not strong enough to support their weight. Any misunderstanding and miscalculation may cause a sudden crash. In 2012, there was an accident occurred involving bungee jumping activity at Victoria Falls, Zambia. In order to identify the level of safeness in bungee jumping activities, this project was conducted to simulate the process when a jumper dives off from a height in such as the maximum diving distance and the maximum lengthening of the bungee cord. An experiment was conducted where the mass represents jumper's weight, elastic cords with different diameter acts as a bungee cord and one meter of iron stand acts like base of jumper standing. This project may give the industry with crucial understanding of this extreme sport. The important of physical quantities likes the maximum elongation of the cord that can be identifying to determine some of safety related issues. In this research, we used Hooke's Law method. Based on the experiment, we got the result that which the suitable weight is good for the certain bungee cord. Therefore, physics could guide to give the answers to a safety questions like "How do I know that the rubber band has the right length and strength for my jump?" and "How am I sure that the g-forces are kept low enough so that the bungee jumping does not hurt?".
