THE MAGIC OF CYCLING​
By: ...
Question:​ Definition of cycling with the laws of physics.
Cycling has been a sport that is enjoyed by a vast amout of people. But what we don't know is that almost the entire spot of cycling is based on physics. Some aspect are obvious like torque and other basic forces but others are not.

Basic Friction in Cyclingexternal image funny_pig_bike.gif
Friction as we all know is produced when two surfaces come in contact and it always oppose motion. Friction in cycling is caused by the wheels on the ground. The friction depends on the moving pieces, ie the wheels, crank, chain, sprocket, gears. Among all these things, the wheels generate the most important friction resistance Rf. It is is proportionate to the square of the speed relatively to the air Va through a coefficient Cf.The use of special wheels helps to reduce friction.
Balanced Force
Kinetic,balanced and unbalanced forces are examples of forces that are in action during the process of cycling. Balanced force constantly acts on the cyclist has he maintains a constant speed. When upward force, friction, gravity and pushing force are exerted on the cyclist a balanced force is obtained.
Rolling Friction
Well filled tyres make cycling a whole lot easier compared to the tyres that are not completely fillled with air. This is due to rolling friction between the tyres and the road.
Force and Motion in cycling
Force and motion are one of the basic physics involved in cycling.When pedaling a bike, the muscles are used to create force. Motion in cycling is produced by the pushing of the pedals. To start a forward motion you push the pedals in a circle. Squeezing the hand brakes exerts a force which stops the motion on the bike.
Gravitational Force in cycling

The amount of gravitational force that is exerted upon a cyclist can be measured with the following formula:Fsl=Wkg9.8 GradHill. Gravitational force is always acting against a cyclist especially when travelling upward on a hill. The two objects that are attracted to each other in this case are: the bicycle and the earth.
Angular Momentum in cycling
Angular Momentum is the tendency of a spinning object to keep spinning in the same directions. It is also the force at work in a gyroscope that makes
wheels want to keep on turning in the same directions and positions as they have been.
The law of Inertia and Cycling
According to Newton's first law, inertia is the tendency for an object that is moving to keep moving and the tendency for an abject that is at rest to remain at rest. This law is obeyed in cycling when the bike is been pedalled fast and then brake. Itdoes not stop immediately and also skid a few inches.
