Question

Friction is a self adjusting force. Justify

Answer 1

we cant walk without the friction

Answer 2

$\large{\underline{\sf{\green{Frictional \: Force-}}}}$

• A type of special Force which opposes the motion of an moving object is termed as 'Frictional Force'.

• It always acts in Opposite Direction of an Object which is in motion.

Eg - Applying Brakes of Cycle, while going down a slide.

$\large{\underline{\sf{\blue{Answer-}}}}$

$\boxed{\sf\red{★ \: friction \: is \: self \: adjusting \: force}}$

• It neither had fixed magnitude & direction.

• It gets adjusted according to Force applied (Applied Force) on the object.

• Static Force can be termed as Adjusting Force.

• Direction of Force applied can be reversed.

Hence, Direction Of Friction is also reversed.

If applied Force increases $\uparrow$, Frictional Force also increases $\uparrow$ in with accordance to it.

$\boxed{\sf{★ \: Hence, \: Friction \: is \: an \: Self \: adjusting \: Force.}}$
