what factors determine the air resistance force on an object ?
When an object free falls, it does not encounter a significant force of air resistance. Always Some Air Resistance. However, a falling object is going to run into some degree of air resistance. Air resistance is the outcome of collisions between the objectâs leading surface and air molecules. How much air resistance the object encounters depends on the speed the object is traveling and the cross sectional area of the object. When the object is falling faster, this increases air resistance.
