Activity 11.6 Class 9 Science Work and Energy
You are suggested to study NCERT activity 11.6 class 9 science
chapter 11Work and Energy explanation with a conclusion so that you can attempt
questions based on activity 11.6 class 9 science.
Activity 11.6 Class 9 Science
· Take
a heavy ball. Drop it on a thick bed of sand. A wet bed of sand would be
better. Drop the ball on the sand bed from a height of about 25cm. the ball
creates a depression.
· Repeat
this activity from heights of 50cm,1m, and 1.5m.
· Ensure that all the depressions is distinctly visible.
· Mark the depression to indicate the height from which the ball was dropped.
· Compare
their depths.
· Which
one of them is deepest?
· Which
one is the shallowest? Why?
· What
has caused the ball to make a deeper dent?
· Discuss
and analyze.
Observation of activity 11.6 class 9 science
When a ball is dropped from a height on a wet bed of sand,
it creates a deep depression.
We drop the ball form different heighti.e.25cm,50cm,1m
and 1.5m.
Now we observe the depths of depression, and we find that the deepest depression is created when the ball is dropped from a height of 1.5m and the shallowest depression is created when the ball is dropped from a height of 25cm.
Explanation of activity 11.6 class 9 science
An object or body possesses potential energy at a certain
height. More the height more the potential energy.
When the ball is dropped from a height say ‘h’, its
entire potential energy is converted into kinetic energy.
Greater is the potential energy and greater is the
kinetic energy.
The ball at a height of 1.5m possesses more potential energy,
when it is dropped, its potential energy is converted into kinetic energy. Due to
greater kinetic energy, the ball creates the deepest depression.
The ball at a height of 25cm possesses less potential energy,
when it is dropped, its potential energy is converted into kinetic energy. Due to
lesser kinetic energy, the ball creates the shallowest depression.
Conclusion of activity 11.6 class 9 science
This activity explains that any object that possesses
energy can do work. More the energy more
the work is done.
