Hello guys,
# Today I would like to share you about physics in real life , I want to share what can we relate with physics when you ride a bicycle . Okay first of all , I want to tell you that I will use two method to explain on this today . I will use the Albert Einstein method and Bloom Taxonomy method . So I hope you will enjoy reading , thanks .

# <center>Albert Einstein Method</center>

> <sup>When you cycling at a constant speed the total force upward are balance by the total force ,total force to the left are balance by total force to the right , this situation is obeying the 3rd Law of Motion or Force of equilibrium .</sup>

> <sup>What will happen if Azizul Hasni Awang bend his body , area is reducing as well as the air resistance also reducing . The rider body shape will become aerofoil shape , then the lifting force is produce, the lifting force which can reduce the resistance between the tyre and the track surface.</sup>

# <center>Bloom’s Taxonomy Method</center>

1.Understanding (Knowledge)
> <sup>For the bicycle moving at constant speed,</sup>
<center>.png)</center>
<sup>Where ,
Ft = Thrust Force
Fr = Friction Force
The resultant force is zero , because the bicycle is moving in at zero acceleration.</sup>
2.Comprehenshion(Understanding The Diagram)
> <sup>The bigger part of the body of the rider is more concentrate at the rear tyre . The reaction force from the rear tyre must be bigger than the front tyre .</sup>
3.Application(Formula Application)
> <sup>When the bicycle moving at constant speed , the vertical forces and horizontal forces are balance to each others .For vertical force,</sup>

<sup>The weight of rider and the bicycle are cancel out by the total reaction forces from the tyre.For horizontal force,</sup>
<center>.png)</center>
<sup>Since the bicycle moving at constant speed, the resistance force is balanced by the thrust force .The resultant force is zero and the bicycle moving with zero acceleration .</sup>
4.Synthesis(Using physics concept to apply into a real life application)
> <sup>By bending your body toward the bicycle handle , the body shape become an aerofoil shape . The speed of air above your body is higher than air below your body .The air pressure below his body is higher than the above your body The different in air pressure will produce a lifting force , This can reduce the air resistance between the tyre and the track surface .</sup>
5.Evaluating (Designing new thing and recommendation)
> <sup>The bigger distance between the seat and handle is designed . If the distance between these two things is bigger , it will make the body easier to bend forward .</sup>

So from this activity we can relate it with #physics ,the Newton’s Third Law or Force in Equilibrium ,this is because reaction force is equal to the action force.The reaction force from the rear tyre is bigger than the front tyre ,this is because the bigger part of the weight of the body of the rider is concentreated on the rear tyre. You need to bending your body toward the handle to increase speed,because the aerofoil shape will form .So the air speed above your body is higher than air below your body .This will make the the air pressure below your body higher than air pressure at your upper body ,lifting force will be produce . The advantages of this lifting force is to make the resistance between the tyre and the track surface reduced . Finally , why I say the bicycle need to be designed to make the distance between the seat is more bigger is to create an aerofoil shape , when you bend your body towad the handle . So , physics is very interesting right ,so I hope you enjoy reading this ,thanks :) .
