Question

find force of friction List the factors affecting the force of friction explain with example briefly

Answer 1

Force of friction: the opposite force which comes into play when one body moves or tend to move and acts between the two surfaces in contact is called force of friction............. Factor on which force of friction affecting are;. nature of the surface . weight of the body tends to slide. For example:when we pull a block by a spring balance the force which act between the table and block opposes the motion is the force of friction which is equal to the applied force on the spring balance gives the reading of the applied force.when another block more force is required to move the set of blocks .This shows that force of friction increase with weight................it is your answer.
