Challenge question.
Will gears let children pull a piano uphill with their bikes? Click the video below to find out.
Yes the children will pull the piano uphill with their bikes
Did you answer the question before or after watching the video? Can you explain why?
After 🙂 the video
Yes the children can pull the piano up hill because if you are on a low gear, it will be easier to pedal uphill even if it makes you go slower. On the other hand, high gear makes you go further but it is harder to pedal.
