Question

22. Define static friction and limiting friction.
​

Answer 1

Answer:

Static friction is a self-adjusting force because it comes into play when the body is lying over the surface of another body without any motion. ... When that body overcomes the force of static friction, the maximum value of static friction is reached, which is known as limiting friction.

Answer 2

STATIC FRICTION

• When two objects having more relative motion between two bodies in contact is called Static friction.
• Static friction help us to start the motion or move.
• For walking on ground or for starting a motion Static friction is necessary.

LIMITING FRICTION

• To start a object motion minimum limiting friction must be applied.
• Direction of limiting friction is always opposite to the direction in which body have to move.
