Angle of friction is the angle between the resultant vector(resultant vector:-resultant vector of frictional force and normalforce) and normal force vector.
1. A child pulls a toy car weighing 0.20 kg across a smooth floor by means of a string attached to it. If the string makes an angle of 60° to the floor and the child pulls with a f
The idea that everything is made up of very small particles has been developed over many years supported by several experiments: (i) Brownian motion :

Angle of friction:For the maximum angle of static friction between granular materials, see Angle of repose.For certain applications it is more useful to define static friction in terms of the maximum angle before which one of the items will begin sliding. This is called the angle of friction or friction angle. It is defined as: where θ is the angle from vertical and µs is the static coefficient of friction between the objects.This formula can also be used to calculate µs from empirical measurements of the friction angle.
