# 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 is it important for the bungee cord to stretch during a bungee jump?

A: After the bungee jumper jumps, he accelerates toward the ground due to gravity. His weight stretches the bungee cord. As the bungee cord stretches, it exerts elastic force upward against the jumper, which slows his descent and brings him to a momentary stop.

## How does bungee jumping work in terms of conservation of energy and impulse?

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.

## What type of potential energy are you seeing when the bungee is stretched?

Elastic potential energy can be stored in rubber bands, bungee chords, trampolines, springs, an arrow drawn into a bow, etc. The amount of elastic potential energy stored in such a device is related to the amount of stretch of the device – the more stretch, the more stored energy.

## What energy transfers happen in a bungee jump?

In a bungee jump, the gravitational potential energy of the jumper is transformed into elastic potential energy.

## How much G force is bungee jumping?

The position y = -L is the point where acceleration a is maximum. For example, if the bungee cord weighs the same as the bungee jumper the maximum acceleration is approximately 1.6g.

## Which force is used in bungee jumping?

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.

## 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.

## 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.

## 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.

## When the bungee cords are released they give the barrel what type of energy?

Potential energy is converted into kinetic energy when bungee cords are compressed / released.

## Do bungee cords follow 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 do you understand by potential energy in a stretched wire?

Elastic potential energy is the potential energy stored by stretching or compressing an elastic object by an external force such as the stretching of a spring. It is equal to the work done to stretch the spring which depends on the spring constant k and the distance stretched.

## What are the 3 main types of potential energy?

There are three main types of potential energy: elastic potential energy, gravitational potential energy, and chemical potential energy. Elastic potential energy is stored in objects that can either be stretched or compressed. The more the object is stretched or compressed, the more elastic potential energy it’ll have.

## 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.

## Why does the bungee jumper not return to the very top of the jump?

The bungee jumper’s gravitational potential energy store increases throughout the ascent. The bungee jumper doesn’t return to the original height. This is because some energy was transferred to the thermal energy store of the surroundings by heating as the rope stretched and then shortened again.

## What are the 4 energy transfers?

• Mechanically – By the action of a force.
• Electrically – By an electrical current.
• By radiation – By Light waves or Sound waves.
• By heating – By conduction, convection or radiation.

## What is the acceleration of bungee jumper?

Between about 2.5 seconds and 4.5 seconds, the jumper is freely falling and the acceleration is near –9.8 m/s2. When all of the slack is out of the bungee cord, the acceleration begins to change. As the bungee cord stretches, it exerts an upward force on the jumper.

## Is bungee jumping a risk?

The extreme forces your body is subject to as it is pulled back upward by the bungee cord can injure the vertebrae of your spine and the delicate spinal cord that they protect. Injuries typically include compression fractures — broken bones in the spine — and herniated discs and spaces between the vertebrae.

## Who should not bungee jump?

Bungee jumping may have health risks for people who are overweight or with injuries. Pregnant women, people with heart problems and high blood pressure are not advised to do bungee jumping.

## Why do people bungee jump?

Conquering Fears Acrophobia or not, voluntarily jumping out of a massive structure or a great height takes guts. Even people who say aren’t afraid of heights would probably break a sweat. The feeling of conquering it though and that sense of achievement which follows is unlike anything in the world.

## How does the kinetic energy of an object change if its speed doubles?

Kinetic energy depends on the velocity of the object squared. This means that when the velocity of an object doubles, its kinetic energy quadruples.

## How do you describe energy transfer?

Energy transfers Energy is transferred by one of the following four types of energy pathway: mechanical work – a force moving an object through a distance. electrical work – charges moving due to a potential difference. heating – due to temperature difference caused electrically or by chemical reaction.

## How do you get down after bungee jumping?

1. Person bungee jumps off a bridge.
2. After a few bounces, the jump is completed.
3. Rope is then lowered down to the person.
4. Person then clips the rope to the bungee harness with a carabiner.
5. Team of operators then pull the person back up to the bridge or platform.
