What is the equation for terminal velocity?

Terminal velocity is the maximum velocity that an object can reach when falling through a fluid, such as air or water. The equation for terminal velocity can be derived from the forces acting on the object.

The equation for terminal velocity is given by:

v = sqrt((2 * m * g) / (ρ * A * C))

where:

  • v is the terminal velocity of the object in m/s,
  • m is the mass of the object in kg,
  • g is the acceleration due to gravity (approximately 9.8 m/s^2),
  • ρ is the density of the fluid in kg/m^3,
  • A is the cross-sectional area of the object perpendicular to the direction of motion in m^2,
  • C is the drag coefficient of the object (a dimensionless quantity that depends on the shape and size of the object).

This equation shows that the terminal velocity depends on the mass of the object, the density of the fluid, the cross-sectional area of the object, and the drag coefficient. Objects with larger cross-sectional areas or higher drag coefficients will have lower terminal velocities.

It’s important to note that this equation is a simplification and assumes that the fluid is incompressible and the forces are acting in a straight line. In reality, factors such as turbulence, fluid compressibility, and the shape of the object can affect the terminal velocity.
