While the Industrial Revolution changed society in far more than just three ways, let us look at some of the largest changes.
Perhaps the most important change was the mass production of goods. Previously, it might have taken a leatherworker an entire day to make a pair of shoes: you had to pay for the shoes themselves as well as the time needed to make them, which made them very expensive. With the onset of the Industrial Revolution, by contrast, a factory could make hundreds of shoes in a day. This dropped the cost considerably: mass-produced goods today are far cheaper than they would be if they were made one at a time.
With the growth of mass production, business owners needed many more workers to run their factories and help machines produce goods. This resulted in the major growth of cities and the depopulation of rural areas, a trend that has continued to this day. People who had previously worked on farms could make more money by moving to cities, thereby helping develop a middle class. However, many cities were not prepared for this mass migration, and crowded conditions and disease outbreaks were common.
However, the Industrial Revolution also demonstrated the abuses of power: workers often had bad pay or dangerous working conditions, and they had to unionize and stand together to get better salaries. This led to the labor movement, which is responsible for aspects of work that we take for granted today, like weekends off and a 40-hour workweek. It also changed political ideologies, helping to develop worker-oriented politics ranging from pure communism to democratic socialism. Today, many nations' political divides can be broadly organized under the categories of worker-oriented (left-wing politics) and business-oriented (right-wing politics).
