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
, the net force is zero, and according to Newton’s Laws, the object maintains a constant Terminal Velocity . The Mathematical Formula Terminal Velocity
You can calculate terminal velocity using the following equation provided by Science Buddies : vt=2mgρACdv sub t equals the square root of
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. : Initially, gravity ( Fgcap F sub g
: Objects with a large surface area (like an open parachute) experience more drag and reach a much lower terminal velocity.
