**What is Terminal Velocity?**

**Terminal velocity** is defined as the highest velocity attained by an object falling through a fluid. As the object falls, the force of gravity initially causes it to continuously speed up as predicted by Isaac Newton. As it gets faster and faster, the air drag force increases until eventually, the air drag force is exactly equal to the force of gravity, and there is no net force acting on the object. If these two forces are exactly balanced, the object will no longer speed up or slow down but will continue falling at a constant velocity, called the **terminal velocity**.

**How to find Terminal Velocity?**

The formulae of terminal velocity is:

$V_t = \sqrt{\frac{2mg}{ρAC_d}}$
