Key difference: They are commonly used words to express obstructions. Obstacles are a block providing obstructions, while hindrance provides obstructions to delay .

An obstacle means ‘any structure that makes progress difficult’.

An obstacle is an obstruction which provides a break in the motion of objects. Obstacles act to stop the work, and thereby reduce the speed of the progress. Smaller obstacles can slow down the flow of the work.

They are generally immaterial things which provide a disturbance to the work. They can be overcome by their respective solving techniques. An obstacle is something which usually stops one for some duration of time. It acts as interruption inbetween the source and the destination.

The meaning of the word hindrance means ‘a thing that provides resistance, delay, or obstruction to something or someone’.

A hindrance is something which provides a disturbance in the form of a delay. It is a form of an interruption which causes the delay. Hindrances are small disturbances, which are supposed to be solved by appropriate methods. If not solved, they may turn into bigger problems.

Hindrances can also said to provide warnings in any work. They are the signs of alertness. They can be solved on their first symptoms. Hindrances provides instability if they occur repetitively.
