The average speed of a substance in a given interval of time is explained as the ratio of the distance done to the time taken whereas; average velocity is explained as the ratio of the displacement to the time taken.
If a particle travels from A to C by a path ABC. Then distance covered is the real covered length ABC, while the displacement is,
Therefore, if the distance covered is and displacement of a particle is in a needed time interval then
The opposition offered to the circular motion of bodies like sphere, disc, ring, cylinder etc. on another surface is known as rolling friction.
