Question

explain with suitable example how effect of normal force on friction forrce​

Answer 1

Answer:

The normal force isn't necessarily equal to the force due to gravity; it's the force perpendicular to the surface an object is sliding on. In other words, the normal force is the force pushing the two surfaces together, and the stronger the normal force, the stronger the force due to friction.

Answer 2

Answer:

hey mate here is your answer ❤️

The force of friction can be found from the following equation. Normal force here is the force that the Earth pushes back on Sam against his mass. Thus, because he is more massive, he will experience a greater normal force and greater frictional force as a result.
