Define :a. static frictionb. dynamic frictionc. rolling frictiond. limiting friction

Answer»

Staic friction
Dynamic friction
Rolling friction and
Limiting friction

Solution :Static friction: The frictional FORCE applied by the surface when the body is at rest is called static friction.
(b) Dynamic friction: The frictional force applied by the surface when the body is in motion is called dynamic friction.
(2) Rolling friction: The frictional force applied by the surface when the body is in rolling motion is called rolling friction.
(d) Limiting friction: The maximum static FRIC- TION is called limiting friction
