Wat is mean by " amount of friction is proportional to size of the normal force"

Well in the case you choose to persue physics or are undertaking specialist maths, you will find that the frictional force is often given by Where is the coefficient of friction and is the normal force on the object.

Due to this, friction is proportional to the normal reaction force.

As the normal reaction force increases so does the frictional force - proportionally (and vice versa)

For example an object is being pulled along a surface. As the normal force on an object is reliant on its weight force, when the mass of the object being pulled increases so does the frictional force acting against the pulling motion so a greater pulling force is required.
