Plzz answer I'll mark as brainliest​

Answer 1

Answer:

HELLO HOPE YOU LIKE IT

Explanation:

The direction of friction is always opposite to the direction of relative motion of two bodies in contact.

For example :in rolling motion of sphere the relative motion of the sphere (at the point of contact between sphere and ground)with respect ground is backwards, and hence friction acts in forward direction ,there by causing motion .

friction is the force that slows things down or prevent things from moving

Answer 2

Explanation:

For example we walk steadily with help of friction becoz the friction between our foot and leg let us steadily walk.We can write in black board with chalk it is due to friction between board and chalk .Thus friction is necessary
