Question

A brick and a feather fall to the earth at their respective terminal velocities. which object experiences the greater force of air resistance?

Answer 1

The brick, even though the brick would end up traveling faster, it most likely has a larger surface area therefore it would have more air resistance.

Answer 2

since brick is heavy than feather so at that time air resistance on brick will be more than the air resistance on feather

Step-by-step explanation:

When an object will reach at its terminal velocity then the acceleration of that object will become ZERO

So at that moment of time we can say that net force on the object must be zero or the force of gravity due to its weight is counter balanced by air friction on the object

So when brick will reach to its terminal speed then we have

`F_air = m_(brick) g`

when feather will reach to its terminal speed

`F_(air) = m_(feather) g`

so here we can say that since brick is heavy than feather so at that time air resistance on brick will be more than the air resistance on feather
