It is easier to roll a barrel than pull it along the road. This statement is

False

True

Uncertain

Not possible

Solution

This phenomenon can be explained by the concept of friction. It is easier to roll a barrel than to pull it on the road because while pulling the barrel because rolling friction is less than sliding friction

Physics

A child weighing $25$ kg slides down a rope hanging from the branch of a tall tree. If the force of friction acting against him is $2\, N$, …….. $m/s^2$ is the acceleration of the child (Take $g = 9.8\,m/{s^2})$

medium

A block of mass $m$ slides along a floor while a force of magnitude $F$ is applied to it at an angle $\theta$ as shown in figure. The coefficient of kinetic friction is $\mu_{ K }$. Then, the block's acceleration $'a'$ is given by: ($g$ is acceleration due to gravity)

A monkey of mass $m$ is climbing a rope hanging from the roof with acceleration $a$. The coefficient of static friction between the body of the monkey and the rope is $\mu$. Find the direction and value of friction force on the monkey.

medium

A small block of mass $m$ is projected horizontally with speed $u$ where friction coefficient between block and plane is given by $\mu = cx$, where $x$ is displacement of the block on plane. Find maximum distance covered by the block
