# Acceleration of Block against Friction

Acceleration of Block against Friction Newton’s second law says that the acceleration (a) of an object is proportional to the force (F) applied on it, and the proportionality factor is the object’s mass (m). Force is a vector quantity, which means we must consider the direction in which it acts. Two main types of frictional Read more about Acceleration of Block against Friction[…]
