A bicycle works by converting the rider's pedaling motion into rotational energy that turns the wheels. When the rider pedals, the chain transfers this energy from the pedals to the rear wheel, propelling the bicycle forward. The wheels provide stability and support while the handlebars control steering.

What type of energy does a spinning bycicle wheel have?
A spinning bicycle wheel has both kinetic energy due to its motion and rotational energy due to its spinning about its axis.
Does it an acceleration if you go around a corner on bycicle?
Yes, when you go around a corner on a bicycle, you are changing your direction of motion, which requires centripetal acceleration towards the center of the curve. This acceleration allows you to turn without skidding off the curve.
What are the types of mechanical work?
The types of mechanical work include static work, dynamic work, and intensive work. Static work refers to work done without motion, dynamic work involves movement, and intensive work focuses on the internal energy changes within a system.
How does input work and out put work affect the efficiency of a simple machine?
Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.
What formula relates work and power?
The formula that relates work and power is: Power = Work / Time. Power is the rate at which work is done, which is the amount of work done divided by the time it takes to do that work.
