Activity 10.1 Class 9 Science
·
Take a piece of thread.
·
Tie a small stone at one end. Hold the
other end of the thread and whirl it around.
·
Note the motion of the stone. Release the
thread.
·
Again, note the direction of motion of the
stone.

Observation Activity 10.1
Class 9 Science Gravitation
When stone is released, it takes a tangential movement and after some time drops
on the ground.
Explanation Activity 10.1 Class 9 Science Gravitation
Before releasing
The stone moves in a circular path and changes direction at every point of
the circle. The change in direction involves a change in velocity.
A force causes acceleration (change in velocity) and keeps the stone moving
along the circular path is acting towards the center (here towards hands) is called
centripetal force.
After releasing
When the stone is released, it moves along a straight line that is tangent
to the circular path. After some distance, it falls down to the ground.
Conclusion Activity 10.1 Class 9 Science Gravitation
This activity 10.1 class 9 science demonstrates centripetal force.
Frequently asked questions
1.
What is the aim of activity 10.1 Class 9 Science?
Ans. This activity asks us to find out the cause of the motion of a stone in a circular path and the motion after releasing it.
2.
What is the cause of the motion of the moon around the earth?
Ans. The motion of the moon around the earth is due to the centripetal
force. This force is provided by the force of attraction of the earth.
3.
What is a tangent to a circle?
Ans. A straight line that meets the circle at one point is called a ‘tangent’
of the circle.
