Q2. Use your brain power and answer the following questions.
i. An iron ball and a plastic ball are released at the same time. They are allowed to fall freely.
Which ball will fall faster ? Why?
Answers
Answer:
CASE 1
CASE 1In air the metal ball will reach first as it is heavier in weight than a plastic ball and air resistance will have very less effect on it as compared to a plastic ball. The air resistance will slow down the plastic ball and may or may not change its path into a parabolic path due to movement of fast air around it. Well I will not discuss this now.

Well I will not discuss this now.CASE 2In vacuum there is no air to resist any of the ball and the time taken by any body does not depend upon its mass. Therefore the metal and the plastic ball will reach at the same moment.
