How does the size of the gears affect the acceleration of solar powered cars?

Answer 1

Solar power doesn't have much to do with it. The following principle is standard for all cars or bikes, despite their power. When a large gear is spinning a smaller gear, the smaller gear will go many more revolutions for every revolution of the larger gear. For example, if we have a gear with a diameter of ten inches and a gear with a diameter of 2 inches, when the larger one rotates once, the smaller one will rotate five times. This helps you in bikes. It is typically recommended that you use a larger gear for larger hills because you will get more out of each pedal, and vice versa for downhill.

Hope this helps :D
