Fun Fact 2: One of the main materials which is capable of producing
elastic energy includes rubber because it is versatile and can be
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
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
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
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
