Question

important topic related to friction class 11☺☺✔✔✔✅✔✅✔✅⭕

Answer 1

friction always acts in opposite direction to force and hence reduces it's velocity. You can directly post the question . Someone will definitely solve them.

Answer 2

friction force is a force in contact force.friction is a force which acts to opposite direction of an object.there are two types of friction.1) static friction 2) sliding friction.

static friction is a friction which acts on between two objects when there are in rest position.

sliding friction is a friction which acts on between two objects when there are in moving position.
