Frictional Force Explained | Learn from BYJU'S

Frictional Force has been explained in this video in a detailed way. Learn what is frictional force in an easy way from this video and read the below-given brief summary about friction below.
What is Frictional Force?
We can define frictional force as the force generated by two surfaces that contacts and slide against each other. If an object is placed flat against another object, then the frictional force will be equal to the weight of the object. If an object is pushed against the surface, then the frictional force will be increased and becomes more than the weight of the object. Some types of frictional forces are dry friction force and fluid friction force.
Example of Frictional Force:
An example of a frictional force is:
To avoid creaking sounds from windows and doors, we lubricate the hinges which lead to the smooth functioning of door hinges.
