questions based on activity 11.8 class 9 science.
Activity 11.8 Class 9 Science
· Take
a rubber band.
· Hold
it at one end and pull from the other. The band stretches.
· Release
the band at one of the ends.
· What
happens?
· The
band will tend to regain its original
length. Obviously, the band had acquired energy in its stretched position.
· How
did it acquire energy when stretched.
Observation of activity 11.8 class 9 science
When a rubber band is pulled, it gets stretched and
when released, it gets its original position.
Explanation of activity 11.8 class 9 science
When the rubber band is pulled, it gets stretched and
energy is stored in it due to work done on it.
The shape of rubber band changes and the energy stored
in it due to a change in the shape is known as ‘Potential energy’.
When the rubber band is released, its potential energy
is used in the form of kinetic energy, and the rubber band gets its original shape.
Conclusion of activity 11.8 class 9 science
This activity explains that energy is stored in any
object when its shape is changed and this form of energy is known as Potential
energy.
