Terminal Velocity 【Top 20 FRESH】
vt=2mgρACdv sub t equals the square root of the fraction with numerator 2 m g and denominator rho cap A cap C sub d end-fraction end-root Definition Terminal velocity Mass of the falling object Acceleration due to gravity ( Density of the fluid (e.g., air or water) Projected frontal area of the object Cdcap C sub d Drag coefficient (based on the object's shape) Key Factors Influencing Speed
: As the object gets faster, the drag force grows until it exactly matches the weight of the object. Steady State : Once Terminal Velocity
You can calculate terminal velocity using the following equation provided by Science Buddies : vt=2mgρACdv sub t equals the square root of
, the net force is zero, and according to Newton’s Laws, the object maintains a constant Terminal Velocity . The Mathematical Formula However, as its speed increases, it collides with
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.
: Heavier objects require more drag to balance their weight, meaning they must fall faster to reach their terminal speed.
