: Heavier objects require more drag to balance their weight, meaning they must fall faster to reach their terminal speed.
When an object starts to fall, gravity is the dominant force, causing it to speed up rapidly. However, as its speed increases, it collides with more air particles, which creates an opposing upward force called air resistance or drag. : Initially, gravity ( Fgcap F sub g ) is much stronger than drag ( Fdcap F sub d ), so the object accelerates downward. Terminal Velocity
: Objects with a large surface area (like an open parachute) experience more drag and reach a much lower terminal velocity. : Heavier objects require more drag to balance
