Terminal Velocity May 2026
: 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
, the net force is zero, and according to Newton’s Laws, the object maintains a constant Terminal Velocity . The Mathematical Formula : Heavier objects require more drag to balance
