(a) Name the kind of frictional force involved in figures 1 and 2.
(b) In which figure would the value of frictional force be more and
why? Explain in detail.​

Answer 1

1. static friction in fig.1 and kinetic friction in fig.2
2. in fig.2 the frictional force is more (equal to the applied force) because there be atleast some force done on it in comparison to fig1 where force act in equal and opposite and cancel out so there is no movement in fig 1
