Friction helps us by letting us grasp things so they won't fall. Without friction you can expect to have more car accidents, and a lot of random people falling because friction helps us walk. Also airplanes in a way use friction to fly.
no slaking in class
You walk and that is the example of friction
An example of a non-frictional force is gravitational force. For example, when an object is in free fall, there is no friction acting on it.
Frictional force depends on the nature of the surfaces in contact and the force pressing them together.
A force can be described by its direction, magnitude, point of application, and type (such as gravitational, electromagnetic, or frictional). It can also be characterized by whether it is a contact force or a non-contact force.
The size of a frictional force is determined by the roughness of the surfaces in contact and the normal force pushing them together. The frictional force opposes the motion of the objects and increases with the weight of the objects in contact.

riding force,Frictional Force
i am sure that it is not frictional force.....

One of the most important frictional forces to humans is the static frictional force that the ground exerts on a body. Without this force, walking would be impossible, cars would go nowhere.
The size of the normal force and coefficient of friction determines the size of frictional force.
The size of a frictional force is determined by the roughness of the surfaces in contact and the normal force pushing them together. The frictional force opposes the motion of the objects and increases with the weight of the objects in contact.
The static frictional force is a self-adjusting force. It increases or decreases to match the applied force, preventing the object from moving until the maximum threshold is reached.
