What else can I help you with?
Is friction considered an external force?
Yes, friction is considered an external force because it acts on an object from outside of it, affecting its motion or resistance to motion.
Why is friction considered a nonconservative force?
Friction is considered a nonconservative force because it does not conserve mechanical energy. When an object moves against a surface with friction, some of its mechanical energy is converted into heat and sound, rather than being conserved. This means that the work done by friction is not reversible and cannot be fully recovered.
Is friction resistance and air resistance the same?
No, Air resistance can be considered as a type of friction however, friction itself is considered to be the a force which opposes motion between two surfaces/substances. For example, A train travelling with a driving force of 500N Has 50N of air resistance acting on it and 75N of friction from the rails. They are considered to be separate.
What does the friction force vs normal force graph reveal about the relationship between friction force and normal force?
The friction force vs normal force graph shows that there is a direct relationship between the friction force and the normal force. As the normal force increases, the friction force also increases. This indicates that the friction force is proportional to the normal force.
How to find the friction coefficient in a given system?
To find the friction coefficient in a given system, you can use the formula: Friction coefficient Force of friction / Normal force. The force of friction is the force resisting the motion of an object, and the normal force is the force exerted perpendicular to the surface the object is on. By dividing the force of friction by the normal force, you can calculate the friction coefficient.
Is friction considered an external force?
Yes, friction is considered an external force because it acts on an object from outside of it, affecting its motion or resistance to motion.
Why is friction a force?
Friction is considered a force because it acts on an item and causes changes, which is what a force is. Nothing would happen if the item was in an area where friction was not possible or if friction was where an object was not since they need each other to exert external effort.
Which has more dragging force water or paste and why?
Paste is considered to have more dragging force. Although water is considered to be denser then paste, paste creates more friction. The higher the level of friction, the greater the drag.

Which is the larger the kinetic friction force or the statical friction force?
Statical friction
What does the friction vs normal force graph reveal about the relationship between friction and the normal force?
The friction vs normal force graph shows that there is a direct relationship between friction and the normal force. As the normal force increases, the friction force also increases. This indicates that the friction force is dependent on the normal force acting on an object.
What is the effect of force on friction?
The force acting on an object increases the friction between the object and the surface it is on. As the force increases, the friction force also increases proportionally until it reaches a maximum value, called the limiting friction. This relationship is described by the equation: friction force = coefficient of friction * normal force.
Is there a force that can go against friction?
No. Friction can only slow an object down. If friction were imparting a force greater than that of the applied forces, then friction in and of itself would actually be causing the object to move, which does not happen.
What are the two factors that affect the friction force between two surfaces?
The strength of the force of friction depends on the types of surfaces involved and on how hard the surfaces push together.
