Q. On which of the following factors does the force of friction depend upon :
- Weight of the body
- Nature of the surface
- Area of the surfaces in contact
Select the correct answer from the codes given below:
Answer:
Only 1 and 2
Notes: The force which opposes the motion of one body over the other is called the force of friction.
- On a horizontal surface, the force of friction is directly proportional to the weight of the body which moves.
- The force of friction depends upon the nature of surface in contact.
- The force of friction doesn't depend upon the area of the surfaces in contact.
