Bicycle gear ratios determine how many times the rear wheel turns for each turn of the pedals. Lower gear ratios make it easier to pedal uphill, while higher gear ratios make it easier to pedal on flat terrain or downhill. Gears work by changing the size of the chainrings and cogs, allowing the rider to adjust the resistance when pedaling.
Gears were invented to make working easier.

A device to make work easier is a machine, such as a lever.
gears make our life easier by changing the direction of the rotation and increasing the the speed of the rotation.

A double over bicycle will have two gears for the chain and it allows for easier pedaling up and down hills. When you are in a low gear, you will find that having the chain on the smaller gear will work better than having it on the large gear, which should be reserved for the high gear.
Machines are designed to make work faster and easier. These machines do so by taking some of the manual work off of you.
It was faster and easier.
False. Friction is a force that resists motion, so it can make work more difficult rather than easier. Minimizing friction can help make work easier.
