Elastic Potential Energy Examples
Until the bow is released the energy used to bend it back is stored as elastic potential energy. Then calculate the elastic potential energy stored due to the.

As weve seen elastic energy can be found in things like elastic bands squishy balls a bow and arrow and coiled springs.
. Examples of Elastic potential energy include sponges rubber bands bungee cords. Springs have their own natural spring constants that define how stiff they are. U s 540 J.
The energy that is stored when a force is used to deform an elastic object is known as elastic potential energy. You will find a thorough explanation of each concept linked with the potential energy of the elastic and spring object for instance Hookes law the relation between the elastic potential energy and kinetic energy. Elastic potential energy may be found in any item that can be distorted and then returned to its original shape.
Here is a list of examples of elastic potential energy to kinetic energy conversion-Bow and Arrow. In the general case of any material the energy stored due to compression or elongation is calculated through the. Position x 0 must always be the position where the spring is most relaxed.
The value of spring constant k is 200 Nm. Arrow is stretchy too. The object may be compressed stretched or twisted during the deformation.
U s ½ 120 -3 2. Elastic potential energy is stored in a spring that has been stretched or compressed by a distance x away from its equilibrium position. When the bow is released the elastic potential energy in the bow is immediately converted into kinetic energy in the arrow.
Also to give practical clarity physics experts at Vedantu have added examples and questions in the notes. It can also be found in catapults and slingshots. Calculate the elastic potential energy.
Elastic potential energy is defined as the energy of an object due to existing damage to its shape. This is the energy stored in an item as a result of its shape distortion. The letter k is used for the spring constant.
Using the formula of elastic potential energy U s ½ k Δx 2. Elastic energy is a form of potential energy in fact its often called elastic potential energy. Elastic potential energy is the energy that is accumulated as a result of the use of.
An archers stretched bow. Elastic Potential Energy Examples. Therefore the elastic potential energy of a spring is 540 J.
Elastic potential energy work done area under the curve of force versus displacement graph Elastic potential energy 05 k x 2. Two balls are connected by a 060 m spring that hits a brick wall compressing the spring to 030 m. When the string pulls on the arrow it bends and flies off the string.
The conversion of gravitational potential energy to elastic potential energy is very much subtle and observed as a linear conversion of energy. A spring is stretched from its rest length of 025 m to 045 m with a spring constant k 180 Nm. The kinetic energy to the arrow is supplied by the conversion of the elastic potential energy of the string which is developed upon stretching the elastic string of the bow and releasing it onto the arrow.
Rubber bands sponges bungee ropes and other similar items are examples. That object is known to have elastic potential energy. For instance in a spring the energy is stored as compressed energy and when released it will convert as elastic potential energy.
It is equal to the force multiplied by the distance moved. Elastic potential energy is the stored energy of a compressible or stretchable object such as a spring rubber band or molecule. U s ½ 120 9.
Let us have a look at the solved numerical problems using the elastic potential energy formula. Elastic Potential energy stored in other plastic materials Spring is an example of an object designed to take advantage of the elastic properties of the material. Until the force is released and the object springs back to its original shape doing labour in the process the energy is retained.
Therefore any random object can be damaged or deformed and then can return to its initial or original shape. What are some examples of elastic energy.
