Terminal velocity is the maximum speed attainable by an object as it falls through a fluid ( air is the most common example). It is reached when the sum of the drag force ( Fd) and the buoyancy is equal to the downward force of gravity ( FG) acting on the object. Since the net force on the object is zero, the object has zero acceleration.
Sep 22, 2022 · Learn what terminal velocity is, how it is reached, and how to calculate it using equations. See examples of terminal velocity for different objects falling through air, water, or viscous fluids.
Learn the definition, formula and examples of terminal velocity, the highest velocity that an object achieves as it falls through a fluid or a gas. Find out how to calculate terminal velocity and test your knowledge with MCQs.
- The maximum velocity attained by an object as it falls through a fluid is called terminal velocity.
- As the object attains terminal velocity, it starts moving with a constant speed in a constant direction because the resultant force acting on the o...
- The size and shape of the object affect the air drag; this, in turn, will affect the terminal velocity.
- There is no drag force in a vacuum; therefore, terminal velocity does not exist.
3 days ago · Terminal velocity, steady speed achieved by an object freely falling through a gas or liquid. An object dropped from rest will increase its speed until it reaches terminal velocity; an object forced to move faster than it terminal velocity will, upon release, slow down to this constant velocity.

Learn how to derive Stoke's law, which relates the viscous drag force on a sphere to its radius, velocity and fluid viscosity. Find out how to calculate the terminal velocity of a sphere falling through a liquid using Stoke's law and its formula.
- Stoke’s Law is an equation that expresses the drag force resisting the fall of small spherical particles through a fluid medium.
- Stoke’s Law states that the force that retards a sphere moving through a viscous fluid is directly proportional to the velocity and the radius of t...
- We use Stoke’s law to determine the terminal velocity, the size and the density of sphere and liquid, respectively. Stoke’s law can also be used to...
- Stoke’s Law is valid for determining viscosity when velocity is constant.
- Settling of sediment in freshwater and measurement of the viscosity of fluids are some of the applications of Stoke’s Law.
Learn how to derive the formula for terminal velocity, the highest speed of an object falling through a fluid, using drag equation and integration. See the steps, assumptions, and examples of terminal velocity in physics.
Jan 24, 2020 · Terminal velocity is defined as the highest velocity that can be achieved by an object that is falling through a fluid, such as air or water. When terminal velocity is reached, the downward force of gravity is equal to the sum of the object's buoyancy and the drag force. An object at terminal velocity has zero net acceleration .
