Question

A leaf falls through the air, floating as it falls. Air resistance is visibly affecting the leaf. Which two properties of the leaf are allowing it to be affected by air resistance?

acceleration due to gravity
initial distance from the ground
mass
surface area

Answer 1

surface area. mass

Step-by-step explanation:

Answer 2

Answer;

Surface area

Mass

Explanation;

• When a leaf falls, it is being accelerated by gravity to the ground but opposed by air resistance also the drag. The net force on a leaf will therefore be calculated by subtracting its weight of the leaf from its drag.
• The air resistance on a leaf is dependent on several physical factors of the leaf: surface area, mass and drag coefficient. Surface area is the size of the leaf while the mass determines the weight of the leaf.
• The fact that a leaf possesses a large area for its low mass means that it has a high drag factor and a relatively low downward speed.
