Answer:
When we pedal uphill, we are working. against the gravitational force that pulls us and the bicycle downwards. The steeper the incline, the more force we need to exert to overcome gravity and maintain our speed. On flat ground, we only need to overcome friction and air resistance, which requires less effort.
