Respuesta :
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.
