Molecules in the air cause air resistance in cars travelling at high speeds. Formula one (F1) racing cars are aerodynamically designed for speed. Find out about these cars, think and answer the questions given below:
a.What is the speed of an F1 car compared to that of an ordinary car?
b.What are the different forces acting on an F1 car? What are their causes?
c.F1 cars are different in shape compared to the cars we see on the road. Why are they of this shape? d.What are the different types of tyres used in races? When are they used?

Answer:
Molecules in the air cause air resistance by exerting an equal and opposite reaction force on objects. If something is hoisted into the air, it bumps into the molecules which react with a similar force that slows the object before gravity takes over. Air molecules have mass which occupy space and it is their cumulative effect that causes resistance.
