Activity 11.12 Class 9 Science Work and Energy
You are suggested to study NCERT activity 11.12 class 9 science
chapter 11Work and Energy explanation with a conclusion so that you can attempt
questions based on activity 11.12 class 9 science.
Activity 11.12 Class 9 Science
· Take
a bamboo stick and make a bow.
· Place
an arrow made of a light stick on it with one end supported by the stretched string.
· Now
stretch the string and release the arrow.
· Notice
the arrow flying off the bow. Notice the change in the shape of the bow.
· The
potential energy stored in the bow due to the change of shape is thus used in
the form of kinetic energy in throwing off the arrow.

Observation of activity 11.12 class 9 science
When the string of the bow is stretched, its shape is
changed and as it is released, again it comes in its original shape.
Explanation of activity 11.12 class 9 science
When the string of the bow is stretched, the bow bends, and
its shape charges. Due to this elastic potential energy is stored in it.
When the stretched string is released, the potential
energy is converted into kinetic energy which causes the arrow covers a large distance.
Conclusion of activity 11.12 class 9 science
This activity explains that due to changes in the shape of
the object, elastic potential energy is stored in the object.
