why is it difficult to balance our body when we accidentally step on a peel of banana give reasons

it is due to friction
 

The surface of banan is smooth so there is very less irregularities. Less the irregularities , less will be the friction. Therefore it is difficult to balance our body if we accidently step on a peel of banana.

This is the answer

Friction

initial ​momentum  = final ​momentum 
Pi = Pf
m​u = mv
here mu is ​initial ​momentum
the​ref​o​re mu is also final momentum
 

Because friction is less in this situation

This happens due to friction because the surface of Bananas very slippery

When we walk on the ground, our foot pushes the ground in the backward direction (action) and the ground pushes our foot in the forward direction (reaction ) . This reaction helps us to move forward. But when our feet fall on a peel of banana, the peel cannot push the ground in the backward direction. Consequently, no reaction force acts on our foot and we lose our balance.
