Rubber Band Bungee Cord Lab

This lab was also used to demonstrate the law of conservation of energy.

Rubber band bungee cord lab.

Students learn about the role engineers and mathematicians play in developing the perfect bungee cord length by simulating and experimenting with bungee jumping using washers and rubber bands. The purpose of this lab was to discover how gravitational potential energy related to elastic potential energy or the energy stored up in the rubber band. She should bounce a bit. Construct a bungee cord composed of 2 rubber bands and attach it to the band on the doll s ankles.

Smartstraps 10 pack assorted length bungee cord. Bungee cord mad of rubber bands. It can be seen that the oscillation does gradually slow down and come to a stop as it undergoes damping. A maximum positive acceleration corresponds to the bungee cord being extended to its maximum.

Determine the mass of the doll on the balance. With two rubber bands now attached to washy hold the end of the rubber band with one hand at the jump line top of the measuring tape and washy with the other hand. Record this value in your observations. Drop washy from the jump line and have one of your groupmates mark the lowest point washy reaches.

Eventually the acceleration is upward although the jumper is still falling. Once again use a slipknot to connect a second band to the bungee line. Just as in the previous situation we took the averages of the three trials we did at each mass in order. An egg hardboiled 3.

Below is an attempt at simulating the bungee jumping scenario using a chain of rubber bands as the bungee cord and a bottle filled with water as the jumper. Hold the band tight at the top of the yardstick and simply let barbie drop from the head down position. Working as if they are engineers for a hypothetical amusement park students are challenged to develop a show stopping bungee jumping ride that is safe. Use a small rubber band to tie back the doll s hair if it is not already in a ponytail.

Item 518169 model 117. In your experiment a block of wood or a toy doll will substitute for the jumper and a rubber band will substitute for the bungee cord. William schirmer daniel clark section. Determining a modified hook s law equation for the bungee cord abstract.

The goal of this lab was to determine an adjusted hook s law equation of the bungee cord by changing the hanging mass on the cord and measuring equilibrium points. Bungee ii lab 4 the data listed in figure 4 shows the data for the bungee cord at the length of 40 cm. Activity activity worksheet 2 8. Remember the band wrapped around her ankles does not count in the length of the line drop her with the two rubber bands attached to her ankles.
