how does the nature of material affect the air resistance acting on it?
Air resistance is a force that slow down objects that are moving through the air
This is because the air is made of particles, like any other material and these rub on the surface of a falling object, the resulting friction slowing down the rate of acceleration due to the downward pull of gravitational force
The greater the surface area of the object, the greater air resistance
Obviously the more surface there is, the greater the number of particles that the falling object is likely to collide with resulting in increased friction.
The faster an object is falling through air, the greater the air resistance
The faster that the object is falling increases not only the frequency of impact but the force of impact which results in greater friction forces acting between the object and the air.
When objects falling to the ground are no longer accelerating but travelling at a constant velocity, the forces of air resistance and gravitational force are said to be balanced
every material has a friction coefficient higher the friction coefficient higher friction it will experience by air.
