Coefficient of static friction ($\mu_s$), kinetic friction ($\mu_k$), and rolling friction ($\mu_r$) generally satisfy the relation:

The maximum speed of a vehicle on a banked road of radius $r$ and banking angle $\theta$ with coefficient of friction $\mu$ is given by:

A block of mass 1 kg is placed on a rough horizontal surface with coefficient of friction $\mu = 0.5$. The maximum frictional force acting on the block is ($g = 10\text{ m/s}^2$):

When a person jumps out of a moving boat, the boat moves backward. This is an illustration of:

To prevent sliding while walking on ice, one should take smaller steps because:
