⠀

$\large\tt\underline\blue{Introduction:-}$

Friction opposes the relative motion between two surfaces in contact. It acts on both the surface. Friction will be greater in case of a rough surface.

⠀

$\large\tt\underline\orange{Aim:-}$

To show that friction produces heat.

⠀

$\large\tt\underline\pink{Materials ~Required:-}$

• Pencil
• Sharpener
• Wooden Board

⠀

$\large\tt\underline\red{Theory:-}$

When two objects are rubbed against each other, heat is produced. Friction depends on the smoothness of surfaces in contact.

⠀

$\large\tt\underline\purple{Procedure:-}$

1. Take a pencil and turn its sharp edge up.
2. Now, tun the edge on the wooden board for one minute.
3. Now touch the edge of the pencil with your cheek.

⠀

$\large\tt\underline\green{Observation:-}$

When you'll touch the pencil edge, it feels hot.

⠀

$\large\tt\underline\blue{Conclusion:-}$

Thus, Friction produces heat

⠀

$\large\tt\underline\orange{Precautions:-}$

1. Rub the pencil edge on the board fast.
2. When you stop rubbing the pencil edge, immediately touch it with your cheek.
