Thanks all for the replies, you certainly know your stuff. I talked with a physics professor and he stated it similarly. I guess the important thing to realize is that potential energy is relative, in the same way someone on the treadmill, not doing work, would move down the treadmill at its...

Thanks for the replies so far, here is my thinking, you do have to provide force to overcome the gravitational force (I didn't think so at first). At an incline of 5 degrees which is 9 percent (this is quite steep) the force I calculated with the sin of the angle 5 with a total mass of bike and...

Hey, guys, my first time posting here but I need some educated individuals to definitively solve a problem from another forum. We are having a discussion about a bike on an incline treadmill (one presumably made for a bike). My contention is that it would still be relatively easy to pedal on...
