What type of potential energy is stored in the bungee cord inside the barrel?

What type of potential energy is stored in the bungee cord inside the barrel?

Elastic potential energy is energy stored as a result of applying a force to deform an elastic object. The energy is stored until the force is removed and the object springs back to its original shape, doing work in the process. The deformation could involve compressing, stretching or twisting the object.

What type of energy is stored when a body is stretched?

The second form of potential energy that we will discuss is elastic potential energy. Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

What are the energy changes in a bungee jump?

As the jumper rises, the energy in the elastic potential energy store of the rope decreases and the bungee jumper’s kinetic energy store increases until the rope becomes slack. After the rope becomes slack, and at the top of the ascent, the bungee jumper’s kinetic energy store decreases to zero.

What type of energy is stored in a stretched balloon?

When you inflate a balloon, it stores potential energy which is energy held by an object because of its position relative to other objects. When you release the inflated balloon, the potential energy is converted into kinetic energy, which is energy in motion.

What is stored energy called?

Potential energy is stored energy and the energy of position.

What type of energy is elastic energy?

mechanical potential energy
Elastic energy is the mechanical potential energy stored in the configuration of a material or physical system as it is subjected to elastic deformation by work performed upon it. Elastic energy occurs when objects are impermanently compressed, stretched or generally deformed in any manner.

Where is elastic energy stored?

Elastic energy is stored in the bonds between the atoms in an object or substance. These bonds absorb energy as they are stressed, and release that energy as they relax. Think of it like a coiled spring – the spring absorbs energy when it is compressed, then releases it when it springs back out.

Are there different types of energy?

Energy exists in many different forms. Examples of these are: light energy, heat energy, mechanical energy, gravitational energy, electrical energy, sound energy, chemical energy, nuclear or atomic energy and so on. Each form can be converted or changed into the other forms.

What is the final potential energy of the bungee cord?

The right hand side of the equation is the final energy, the potential energy of the bungee cord when it is fully stretched. Gravitational potential energy has been converted into potential energy of the bungee cord. This equation is quadratic in h. When we solve for h, we obtain two values, 0.11 m and 2.39 m.

What is the size of the bungee cord?

The bungee cord is surgical tubing, about 1/8 inch in outer diameter. We first determine the “spring constant” kof the bungee cord. Cosmo’s mass is m= 1.13 kg.

What forces are involved in bungee jumping?

The third force the jumper experiences is a spring force due to the bungee cord. The amount that the bungee cord pulls back on the jumper depends on how far the cord has been stretched, i.e. the farther the jumper has fallen, the more the cord pulls back on him or her.

How do you calculate the spring constant of a bungee cord?

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
