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.

      

Activity 10.1 Class 9 Sciecne

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.
