Fun Fact 2: One of the main materials which is capable of producing elastic energy includes rubber because it is versatile and can be stretched.
Fun Fact 3: When a material is stretched, it produces elastic energy, however, the material can be over-stretched or twisted which may cause it to break.
Fun Fact 4: When elastic energy is produced, the object in question is being stretched. Providing it is not over-stretched, the object should be able to return to its original shape.
Fun Fact 5: Some good examples of objects which can be stretched to produce elastic energy are: rubber bands, balloons, springs, catapults and trampolines.
Fun Fact 6: The examples above are able to return to their normal shape once released and they stop producing elastic energy.
Fun Fact 7: The following example provides a safe experiment to try at home: If you blow a balloon up, the material stretches causing it to produce elastic energy. If you tie the balloon, it will retain its elastic energy. However, if you release the air from the balloon, it will return to its original shape.
Fun Fact 8: Elastic energy can be described as the power produced when an object's shape is being configured or expanded.
Fun Fact 9: When elastic energy is released, it can cause an object to travel quite far. A catapult or elastic band provide good examples of the speed an object can travel at due to the result of this type of energy.
Fun Fact 10: A coiled spring is another good example as it can be stretched quite far, deforming its shape but allowing it to return to its original shape once released.
Fun Fact 11: Elastic energy can be produced when you stretch a muscle in your body!
Fun Fact 12: When an object is stretched, for example a rubber band, it increases in length. This is known as its extension.
Fun Fact 13: What is the formula to determine the force of elastic energy? The force of elastic energy can be worked out using this simple equation: F = k x e
Fun Fact 14: The above equation can only be used if the object is not over-stretched. You will know if an object is over-stretched as it will no longer return to its original shape and size.
Fun Fact 15: If you are struggling to understand the equation, the following explanation will help:
F = the force measured in newtons
k = the 'elastic band constant' in newtons per metre
e = the length of the stretched band in metres
