Terminal velocity is the maximum velocity an object can attain as it falls through a fluid medium, such as air or water. At this point, the gravitational force pulling the object downwards is balanced by the medium’s resistance, resulting in a constant velocity.

Factors Influencing Terminal Velocity:

1. Object-related factors:

  • Mass: Heavier objects experience greater gravitational force, which tends to accelerate them more. As a result, heavier objects typically have higher terminal velocities than lighter objects.
  • Shape: The object’s shape affects its interaction with the fluid medium. Objects with streamlined shapes experience less air resistance and can reach higher terminal velocities than irregularly shaped objects.

2. Fluid-related factors:

  • Density Of The Fluid: The density of the fluid through which the object is falling influences the resistance it encounters. Denser fluids, such as water, provide more resistance, affecting the object’s terminal velocity.
  • Viscosity Of The Fluid: Viscosity refers to the fluid’s resistance to flow. Fluids with higher viscosity, like honey or molasses, exert more resistance on the falling object, impacting its terminal velocity.

3. Environmental factors:

  • Altitude: Atmospheric pressure and density decrease with altitude, affecting the resistance experienced by the falling object. Higher altitudes generally result in lower air density and reduced resistance, potentially increasing terminal velocity.
  • Temperature: Air temperature can affect the density and viscosity of the fluid medium. Warmer temperatures typically lead to lower air density and viscosity, which may influence the terminal velocity of the falling object.
