Take a look at a bicycle with gears. Using what you have just learned, answer the following questions: 1. Which gear combination would you like to use when you want to pedal with as few strokes as possible and have your wheels turn as many times as possible?
2. Now you are going up a hill and want to maximize the force you deliver to the wheel. You aren’t concerned with how many strokes you are making, but you want to get as much force to the wheel as possible. Which gear combination would you use now, and why?
