Why does A stretched elastic or stretched string each have potential energy?

Think of a Bowling ball sitting on a shelf. The ball itself is no different from a bowling ball sitting on the floor, but one of them contains enough potential energy to break the bones in your foot if you drop it.
The energy that is converted when you stretch the elastic or string from its relaxed state is called potential energy by analogy, even though there's really no potential field equivalent to gravity.

When a stretched string is released the potential energy in the string is converted to?
kinetic energy
When a stretched string is released the potential energy in the string is convrted?
Into movement, i.e., kinetic energy.
What type of energy increases when you compress a string?
elastic potential energy
What are the energy transformations when an archer pulls the string on the bow and when the archer releases the bow?
The energy in the stretched bowstring is potential energy - specifically, elastic energy. This is converted into kinetic energy, when the arrow is released.
Would a catapult have potential energy?
Yes or it can have elastic energy(search it up)if it has a string/rope of some sort I think

What energy do we give to a strong if we stretch it?
It should be string. That is elastic potential energy

Are there physics behind bungee jumping?
The energy changes that happen during a bungee jump are:Gravitational Potential Energy (GPE) changes into elastic potential energy and kinetic energy as the string starts to stretch and the person starts to fall.When the person is at the bottom, GPE is changed into elastic potential energy as the string is stretched further.As the person rebounds, elastic potential energy is changed into kinetic energy and GPE as the person moves upwards and they get higher.

is there potential energy in guitar strings if not why?
The potential energy in a guitar string can be calculated from PE = integral F dx, where x is the distance the string is stretched. Using Hooke's Law, F=kx, where k is the elastic modulus, and x is the distance the string is stretched. Putting it together, PE = integral kx dx PE = 1/2 k x^2. The value of x varies depending on the tuning and the size of the guitar, and the value of k varies depending on the type of string used. As an example, say a typical guitar string has a tension of about 60 Newtons, and is stretched by 5 cm. From this we can find k = 1200 kg/s^2. Fully stretched, PE = 1/2 (1200) (0.05)^2 = 1.5 Joules.
When a stretches string is released the potential energy in the string is converted to?
kinetic energy
How does a yo yo transfer potential energy to kinetic energy and back again as it moves up and down its string?
Before a yo yo is released, it has maximum potential energy and zero kinetic energy. As the yo yo goes down the string, its kinetic energy increases and it potential energy decreases. When the yo yo reaches the bottom of the string it has maximum kinetic energy and zero potential energy. As the yo yo goes back up the string, its kinetic energy decreases and potential energy increases until the yo yo reaches the top of the string, at which point kinetic energy is zero and potential energy is at its maximum.
