Chapter 6, Problem 17A

If two objects of the same size fall through air at different speeds, which encounters the greater air resistance?

To determine

The object that will encounter the greater air resistance.

Explanation of Solution

Introduction:

The velocity of falling object decreases by the air resistance.

The air resistance depends on speed and surface area of object.

As object is falling with different speed the object with high speed experience greater air resistance.

The object falling with less speed experience less air resistance.

Conclusion:

High speed object experiences greater air resistance than low speed object.
