Rubber Band Bungee Cord Lab

A maximum positive acceleration corresponds to the bungee cord being extended to its maximum.

Rubber band bungee cord lab. 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. This lab was also used to demonstrate the law of conservation of energy. 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. Bungee ii lab 4 the data listed in figure 4 shows the data for the bungee cord at the length of 40 cm.

For the bungee cord. 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. Record this value in your observations. Use a small rubber band to tie back the doll s hair if it is not already in a ponytail.

Construct a bungee cord composed of 2 rubber bands and attach it to the band on the doll s ankles. Item 518169 model 117. 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. Determining a modified hook s law equation for the bungee cord abstract.

An egg hardboiled 3. William schirmer daniel clark section. It can be seen that the oscillation does gradually slow down and come to a stop as it undergoes damping. She should bounce a bit.

Lab report outline bungee lab 1 your name and your lab partner s. 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. Drop washy from the jump line and have one of your groupmates mark the lowest point washy reaches. 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.

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. 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.

Determine the mass of the doll on the balance. Activity activity worksheet 2 8. Create a safe bungee cord for washy. Bungee cord mad of rubber bands.
