Explain the concept/nature of frictional
force.​

Answer 1

Answer:

hi!!

your answer:

Frictional Force refers to the force generated by two surfaces that contacts and slide against each other. ...

pls mark me as brainliest if u see this helpful

Answer 2

$\huge\underline{\underline\mathtt{Answer:-}}$

When two bodies press directly against each other and when there is relative motion between them, or even a tendency, the bodies exert frictional forces along their surfaces of contact. On each body, this force acts opposite to the direction of its motion, or opposite to the direction in which it tends to move.

The force of static friction resists the attempt to set one body into motion across the surface of another. Till the relative motion begins, the force of static friction is self-adjusting, meaning that its magnitude always remains equal to that of the applied force. The relative motion begins once the applied force just exceeds this limiting force of static friction

Once the relative sliding motion begins, the force of friction that resists the subsequent relative motion is called the force of kinetic friction. This force being less than the limiting force of static friction, a smaller force is required to maintain the motion.
