Question

3 Does the normal force of an object effects
the frictional force?​

Answer 1

Answer:

Friction is proportional to the force with which an object pushes against the surface you're trying to slide it along. 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.

so, yes it does

Answer 2

Friction is proportional to the force with which an object pushes against the surface you're trying to slide it along. ... 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.
