Question

can someone explain the graph of applied force wrt friction force??​

Answer 1

Answer:

The frictional force opposing the motion of the crate is equal to the applied force but acting in the opposite direction. This frictional force is called static friction. When we increase the applied force (push harder), the frictional force will also increase until it reaches a maximum value.

Answer 2

-->In this graph, Frictional force is negative because it is

   opposing the applied force.

-->Initially the Frictional force is increasing along the applied

   Force. This is static Frictional Force. Its magnitude is eqaul to        that of applied Force till it reaches its maximum limit.

-->When reaches its max limit it lowers to a point and then the

   Frictional Force becomes constant. This is Kinetic Frictional

   Force.
