There are 3 forms of energy during a bungee jump, kinetic (KE = 0.5mv^2), gravitational potential (GPE = mgh) and elastic potential (EPE = 0.5kx^2). Energy is conserved throughout, and it’s assumed none is lost as heat due to air resistance.

How does bungee jumping relate to physics?
Bungee jumping is a thrilling, spectacular and mind blowing sport. In terms of physics, it correlates to a variety of diverse properties and topics. Such as energy, momentum, gravity, forces and resistance. In terms of energy, bungee-jumping involves both potential and kinetic energy.
How do you calculate the energy stored in a bungee cord?
Potential energy of the bungee cord: The potential energy of the bungee cord is (1/2)kx2, where x is the amount by which the cord is stretched.
How is bungee jumping calculated?
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 does a bungee cord stretch as well as it does 1 point?
As you stretch or compress an elastic material like a bungee cord, it resists the change in shape. It exerts a counter force in the opposite direction. This force is called elastic force. The farther the material is stretched or compressed, the greater the elastic force becomes.
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.
What is the force constant of the bungee cord?
Question 5 : BUNGEE The spring constant of the bungee cord is 50 N/m (newtons per metre).
Which is considered as the energy of motion?
The energy associated with an object’s motion is called kinetic energy.
How do you calculate stored energy?
- Work is done when a spring is extended or compressed . Elastic potential energy is stored in the spring.
- The elastic potential energy stored can be calculated using the equation:
- elastic potential energy = 0.5 ร spring constant ร (extension) 2
What is the equation used to calculate elastic potential energy?
Looking at a graph of force versus displacement, we can find that the formula for elastic potential energy is PE = 1/2(kx^2).
How do I calculate potential energy?
In this example, a 3 kilogram mass, at a height of 5 meters, while acted on by Earth’s gravity would have 147.15 Joules of potential energy, PE = 3kg * 9.81 m/s2 * 5m = 147.15 J.
How is energy conserved during a bungee jump?
The law of conservation of energy states that energy can not be created or destroyed, only converted between one form and another. 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).
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.
Does weight matter 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.
How is energy transferred calculated?
Energy transferred electrically is calculated using the equation ฮE = IVt , where I is the current, V is the potential difference and t is time.
How is energy transferred physics?
Thermal energy transfers occur in three ways: through conduction, convection, and radiation. When thermal energy is transferred between neighboring molecules that are in contact with one another, this is called conduction.
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 calculate the extension of a bungee cord?
Equating these expressions gives mgh = 0.5kx^2. This assumes that all of the gravitational potential energy of the bungee jumper will be converted to elastic potential energy. To find the maximum extension of the rope, rearrange this expression to find x, giving x = (2mgh/k)^0.5.
Is shock cord the same as bungee cord?
Bungee cord, shock cord, and elasticated cord are three names that are used interchangeably, to describe a cord with a stretchy rubber core and a braided outer sheath. In fact, all of the bungee cords available on our site are actually listed as shock cords, because they’re exactly the same thing!
How much weight can bungee cords hold?
Bungee Cord – Shock Cord Shock cord, commonly known as bungee cord, is available in a variety of diameters ranging from 1/8 inch with a tensile strength of 100 pounds to 1/2 inch with a tensile strength 450 pounds.
Can we store energy in a bungee cord?
What happens when potential energy is turned into kinetic energy?
Energy is never destroyed or lost when changing from potential energy to kinetic energy โ it is merely transformed from one energy type to another. This is known as the law of conservation of energy.
What are three other forms that electrical energy can be turned into?
Electrical energy is transformed into many forms – mechanical/kinetic, sound, heat, light, and other forms of electromagnetic radiation – by everyday appliances.
How does spring constant affect bungee jumping?
We hypothesize that the spring constant k will vary with the bungee length inversely. This means that as the bungee length increases, the spring constant k will decrease.
