Question

The Bora of friction always acts against..........The motion.

Answer 1

It is defined as the force that operates in the opposite direction to reduce the magnitude of the employed force. Mathematically, it is equal to the multiplication of normal force and coefficient of friction force.

Frictional force always acts against the motion of an object, or it counters the motion of an object over the other surface. If the frictional force increases, it will reduce or cancel out the force causing the motion. The increasing value of force operating on the object tends to accelerate the object.

Thus, if the frictional force employed on an object reduces, the object will accelerate, or the value of acceleration will improve.
