It begins to slide when mgsin(theta) i.e. force due to weight along the incline becomes greater than the force of friction.

Answer:

Objects are known to accelerate down inclined planes because of an unbalanced force. ... The force of gravity (also known as weight) acts in a downward direction; yet the normal force acts in a direction perpendicular to the surface (in fact, normal means "perpendicular").
