After a brief introduction, set up the lesson by telling students that they will be creating a bungee jump for a Barbie® doll. Their objective is to give Barbie the greatest thrill while still ensuring that she is safe. This means that she should come as close as possible to the ground without hitting the floor.

What are the forces acting on a bungee?
During the bungee jumper’s fall, he or she also experiences a force due to air resistance. The faster the jumper is falling, the more the air resistance pushes back opposite to the direction of motion through the air. The third force the jumper experiences is a spring force due to the bungee cord.
How does the law of inertia apply to bungee jumping?
When a bungee jumper is falling, the property of inertia explains how they want to keep falling. The object in movement, the bungee jumper, wants to stay in motion, as we know because if there was not an external force, such as the bungee or the ground, the bungee jumper would continue to fall.
How do you make a Barbie bungee?
Does the bungee cord obey Hooke’s Law?
Hooke’s Law tells us that the elastic bungee cord will stretch by a known amount for each person depending on their weight. Elastic objects stretch by the same amount each time we add the same amount of weight or force until it reaches its elastic limit.
What type of energy is in a bungee jump?
During a bungee jump, the stored, potential energy (PE) of the jumper on a tall platform (PE = mgh) is converted into kinetic energy (KE) during the fall (KE = 1/2mv2). This kinetic energy is converted back into potential energy as the bungee cord (rubber band chain) stretches.
Why is bungee jumping simple harmonic motion?
Bungee jumping is a good example of simple harmonic motion. Bungee jumping companies have a variety of cords so that people of different weights can take the jump without hitting the bottom. It’s similar to the egg drop lab that we did, but with different variables, and the height of the drop being the constant.
What is Barbies last name?
HISTORY. Barbie’s full name is Barbara Millicent Roberts. Barbie was named after Ruth Handler’s daughter, Barbara, and Ken after her son, Kenneth. She is from (fictional) Willows, Wisconsin, where she attended high school.
What’s Ken’s real name?
According to the 1960s Random House books, Ken’s full name is Kenneth Sean Carson.
Why did Barbie and Ken break up?
February 14, 2004: Barbie and Ken officially broke up. The newspaper assigned the split to Ken’s failure to commit and Barbie’s excitement to commit, wearing multiple wedding gowns. This was also a year that Barbie ran for president, so she was quite busy.
Is bungee jumping a Newton’s law?
Newton’s third law can be related to a very specific part of a bungee jumping system. That is, the point in which the bungee is completely stretched out and the jumper is actually at rest. At this specific point, where the bungee is stretched out and the jumper is about to be sprung back upwards.
At what point does the bungee jumper have the most kinetic energy?
The maximum kinetic energy will occur when the tension in the elastic is equal to the force of gravity on the descending jumper: so that Below this point the jumper will start to decelerate.
What is the formula for bungee jumping?
We calculate the spring constant of the bungee cord: k = F/x = mg/x = 15.2 N/m. If we release Cosmo at the position where the other end of the bungee cord is attached, he falls until the force of the stretched cord finally stops him at the bottom of his fall.
Will a bungee cord forever hold its shape Why or why not?
After the elastic limit is an area called the plastic region. The object may be stretched further in this area, however it will not returned to its original shape and will be permanently distorted.
Is bungee jumping an oscillation?
The above described phenomenon is known as a damped oscillation and in the case of bungee jumping, a lightly damped oscillation will occur, whereby the displacement against time graph of the system will show a exponentially decaying envelope.
How much work is required to stretch the cord by this much?
(d) How much additional work is required to make the cord stretch twice as much? Since the extension is double and the work is proportional to the square of the extension then the work required is 4 times as great. Which means 4 × 5880 = 23500 J is needed.
How does bungee jumping relate to physics?
The gravitational force is almost exactly constant throughout the jump. During the bungee jumper’s fall, he or she also experiences a force due to air resistance. The faster the jumper is falling, the more the air resistance pushes back opposite to the direction of motion through the air.
Why do you have potential energy at the top of a bungee?
Why is weight important in bungee jumping?
How much you weigh will make a big difference to how the bungee jump performs, and therefore how the operators need to set it up. They will get your weight and then calculate which rope category you need to jump from. If a lighter jumper goes first, they will have a different rope to a heavier jumper who goes next.
Do you reach terminal velocity when bungee jumping?
When you’re bungee jumping, you will not be able to reach terminal velocity. Therefore, you will feel unstable during the whole experience. This is one of the reasons some people feel more disoriented and out of control during bungee jumping vs. skydiving.
What are some examples of simple harmonic motion?
The pendulum oscillating back and forth from the mean position is an example of simple harmonic motion. Bungee Jumping is an example of simple harmonic motion. The jumper oscillating up and down is undergoing SHM due to the elasticity of the bungee cord.
Is Midge Barbie’s sister?
Margaret “Midge” Hadley Sherwood is a fictional doll character in the Barbie line of toys by Mattel that was first released in 1963. Midge was created at the same time as Skipper. She was marketed as Barbie’s best friend.
Is Barbie a mom?
Barbie has been the woman who can do anything and everything yet in all that time, Barbie has never become a mom. There are a few possible reasons for that but the likeliest one is that Mattel has simply never really envisioned Barbie in a mom role.
Is Skipper Barbie’s sister?
Skipper. Skipper is Barbie’s first sister who debuted in 1964. She was Barbie’s little sister back then and was 10 years old when she was first introduced.
Is there a black Ken doll?
Customers can now choose from a number of Kens, including Black, Asian and Brown ones.
