Terminal Velocity Calculator


About Terminal Velocity Calculator (Formula)

The Terminal Velocity Calculator is a tool used to compute the maximum velocity reached by an object falling through a fluid (usually air) due to the balance between the gravitational force and the drag force. Terminal velocity occurs when the object’s acceleration becomes zero because the forces acting on it are in equilibrium. The formula for calculating terminal velocity is as follows:

Terminal Velocity = √((2 × (Weight of Object)) / (Drag Coefficient × Air Density × Cross-sectional Area))


  • Terminal Velocity: The maximum velocity that an object reaches during free fall due to air resistance.
  • Weight of Object: The force exerted on the object due to gravity, equal to its mass multiplied by the acceleration due to gravity.
  • Drag Coefficient: A dimensionless constant that represents the object’s shape and how it interacts with the fluid.
  • Air Density: The density of the air through which the object is falling.
  • Cross-sectional Area: The effective area exposed to the fluid resistance.

Terminal velocity is a crucial concept in physics, especially in the study of fluid dynamics and free fall motion. It’s influenced by factors such as object mass, shape, size, and the density of the fluid through which the object is falling.

The Terminal Velocity Calculator aids in understanding the factors that affect an object’s terminal velocity, making it a valuable tool for students, researchers, and those interested in the dynamics of falling objects in fluids.
