Bullet train
Transcript: Aeroplane Airplane’s wings are curved on top and flatter on the bottom to make air flow over the top faster than the bottom. GROUP MEMBERS: NORZAINI ROS BINTI NOR SHAHFIZA BINTI NUR AMIRAH BINTI MAT GHANI NOORUL ATIQAH BINTI RAMLI CONCLUSION Non- aerodynamics cars The air flows become irregular or turbulent above a certain velocities The flow will abrupt the velocity of the car CONCLUSION Bicycles Aerodynamics shape can be improved by the body shape of the riders Bullet train Body shape of the train is streamline and the front part of the bullet train is tapered like nose of aeroplane to reduce air resistance as much as possible. VEHICLE AERODYNAMICS HOW AERODYNAMICS WORKS?? When air flows over a body having a streamline shape, the flow is faster across the curved surface compared to flat surface. Bernoulli’s principle is applied Four forces involved HOW AERODYNAMICS CARS SAVE ENERGY? Vehicle aerodynamics How aerodynamics cars save energy?? Bullet train Body shape of the train is streamline and the front part of the bullet train is tapered like nose of aeroplane to reduce air resistance as much as possible. WHAT IS AERODYNAMICS? The study of movement of air over a body in motion How aerodynamics cars save energy?? Aerodynamics cars The air flow smoothly around the car is said to be laminar The laminar flow does not abrupt the velocity of car.

Differences between aerodynamics cars and non-aerodynamics cars. Aerodynamics cars is created to reduce aerodynamic drag. The greater the drag, the harder the vehicle motor has to work At high speed, aerodynamics drag can be the largest consumer of energy on a heavy vehicle. What is aerodynamics?? Vehicle aerodynamics Movement of air over a body in motion How aerodynamics work? When air flows over a body having a streamline shape, the flow is faster across the curved surface compared to flat surface. Bernoulli’s principle is applied Four forces involved Vehicle aerodynamics Overall, it is obvious that aerodynamics vehicles can conserve energy. It is because the air flows smoothly around an aerodynamics vehicle. From Islamic perspective, aeroplane was first invented by Abbas Ibn Firnas using the concept of how bird can fly,Do they not observe the birds above them, spreading their wings and folding them in? None can uphold them except ((Allah)) Most Gracious: Truly ((Allah)) Most Gracious: Truly it is He that watches over all things.(Al-mulk:verses 19) In Islam we have been taught to not wasting and it is clearly stated in Surah Al-Isra’(verses 27): Indeed, the wasteful are brothers of the devils, and ever has Satan been to his Lord ungrateful.
