Question

Define the terms static friction limiting friction and kinetic friction

Answer 1

STATIC FRICTION is the force opposing a push or pull on a body.

LIMITING FRICTION is the friction at which a body just begins to move but is not quite moving yet.

KINETIC FRICTION is the opposing frictional force on a body which is in motion.

Answer 2

Answer :-

☄Static Friction:−

• When two objects having more relative motion between two bodies in contact is called Static friction.

• Static friction doesn't exist by itself.

• 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:−

• It is the maximum opposing force that comes into play, when one body is just at the verge of moving over the surface of the other body.

OR

• It is the maximum value of static friction between surfaces of 2 object if applied force is increase beyond it to the object start, having realtive motion.

• To start a object or for starting a motion minimum limiting friction value must be applied.

• The direction of force of limiting friction is always opposite to the direction in which body have intension to move.

☄Kinetic Friction:−

• It is the opposing force that comes into play when one body is actually moving over the surface of another body.

OR If their is a realtive motion between bodies which is in contact is known as kinetic Friction.

• Kinetic Friction help us to stop the motion.

• Kinetic Friction is always slightly less than the limiting friction.

• Kinetic Friction is also known as dynamic friction.
