What is the effect of air resistance on the acceleration of falling objects? What is the acceleration with no air resistance?
ANSWER: A freely falling object experiences weightlessness and an acceleration of 9.8 m/s . this increases the speed of the falling object gradually. If there would be air resistance, then it works like a drag force and the acceleration decreases and this causes a decrease in speed too. The person falling in such case will not feel the weightlessness. Because of the air resistance , some amount of normal reaction he would get. And the weight is defined as the net normal reaction an object gets. But if there will be no air resistance, the acceleration of the object would be exactly equals to 9.8 m/s and the person who is falling will feel his weight as zero. The normal reaction he would get is zero.
