Question

Four students were asked to arrange the (frictional) forces, due to rolling, static
and sliding friction, in an increasing order. Their arrangements are listed below.
The correct arrangement is
rolling, static, sliding
static, sliding, rolling
rolling, sliding, static
static, rolling, sliding​

Answer 1

Static, sliding, and rolling friction occur between solid surfaces. Static friction is strongest, followed by sliding friction, and then rolling friction, which is weakest. Fluid friction occurs in fluids, which are liquids or gases.
