Activities

[Author - Kripa S]

1. Make an inclined plane on a smooth floor, or on a table. You may use a wooden board supported by bricks, or books. Put a mark with a pen at any point on the inclined plane. Now let a pencil cell move down from this point. How far does it move on the table before coming to rest? Note down the distance. Now spread a piece of cloth over the table. Make sure that there are no wrinkles in the cloth. Try the activity again.
