Click For Summary
Pedaling a bicycle involves the application of torque, which is the rotational force generated by the rider's legs. This force is transferred through the bike's chain to the rear wheel, propelling the bicycle forward. Friction plays a crucial role in this process, as it affects the grip of the tires on the road and the efficiency of the drivetrain. Understanding these concepts is essential to grasp how pedaling translates into motion. Overall, the mechanics of pedaling encompass various physical principles that contribute to the bicycle's movement.

It is referring to motion ¨terms¨ like friction and rings like that.

Uh, torque? I don't understand what exactly you are looking for.
 

Thread 'Is this a coincidence?... (distances between planets)'

I'm not a student or graduate in Astrophysics.. Wish i were though... I was playing with distances between planets... I found that Mars, Ceres, Jupiter and Saturn have somthing in common... They are in a kind of ratio with another.. They all got a difference about 1,84 to 1,88x the distance from the previous planet, sub-planet. On average 1,845x. I thought this can be coincidential. So i took the big moons of Jupiter and Saturn to do the same thing jupiter; Io, Europa and Ganymede have a...
