Are you eager to know the speed of terminal velocity? So, stay connected because here we will give you all information regarding the terminal velocity. As you move higher when you jump, the more it hurts on hitting the ground. Why? It is because the Earth’s gravity is constantly accelerating you towards its center. But there is actually a maximum speed you reach, where the acceleration of the earth’s gravity is balanced by the air resistance of the atmosphere. The maximum speed is called terminal velocity. Let’s move forward and know the exact speed of terminal velocity.
What Is The Speed Of Terminal Velocity?
The speed of terminal velocity is 150 miles per hour or 240 kilometers per hour. Now, you what is the speed of terminal velocity in mph. but, the question is what is the fastest terminal velocity? So, the fastest terminal velocity is about 134 km/h. This is about the exact same velocity achieved by a peregrine falcon diving for prey or for a bullet falling down after having been dropped or fired upward. The world record terminal velocity was set by Felix Baumgartner, who jumped from 39,000 meters and reached a terminal speed of 134 km//h, which means 834 mph.
Your next question should be, how long does it take to reach terminal velocity? So, you need only 12 seconds to reach the terminal velocity. The terminal velocity in air is the maximum velocity attained by an object as it falls through a fluid, and the air is the most common example. It occurs when the sum of the drag force and the buoyancy is equal to the downward force of gravity acting on the object.
How fast is the terminal velocity for a human? So, for a human being the fast terminal velocity is about 120 mph.
Now, you know what’s the speed of terminal velocity as well as the speed of terminal velocity mph. Let’s know how to calculate terminal velocity.

Calculate The Speed Of Terminal Velocity
So, to calculate the speed of terminal velocity you need to multiply the mass of the object by the gravitational acceleration. Divide the resultant by the product of drag coefficient and projected area. You can also calculate the terminal velocity by using the terminal velocity calculator. Let’s follow the given procedure,
- Multiply the mass of the object by the gravitational acceleration.
- Now, divide the resultant by the product of drag coefficient and projected area.
- Multiply the number in the previous step by 2.
- Then divide the product by the density of the fluid.
- Obtain the square root of the result to get the terminal velocity of the object.
Let’s understand with the help of an example.
A baseball with a circumference of 9.25 inches and 5.5 oz mass. The coefficient of drag for the baseball is taken as 0.3275 then find the terminal velocity of the baseball.
So, terminal velocity of baseball = √((2 × 0.14883 × 9.81)/(1.2041 × 0.004393 × 0.3275))
= 40.7 m/s
= 91.84 mph
The terminal velocity of the baseball is 91.84 mph.
About Terminal Velocity
Terminal velocity is the maximum velocity attained by an object as it falls through a fluid. It occurs when the sum of the drag force and the buoyancy is equal to the downward force of gravity acting on the object. An animation can help visualize this concept, showing how the forces acting on an object change as it falls through the fluid and approaches its terminal velocity. Understanding terminal velocity is important in many fields, including physics, engineering, and skydiving
Terminal velocity depends upon the weight of the falling object and the surface area and what it’s falling through. For example, a feather doesn’t weigh much and presents a very large surface area to the air as it falls. So, its terminal velocity speed is much slower than a rock of the same size because the rock is heavier than a feather.
Is terminal velocity constant? Yes, the constant vertical velocity is called the terminal velocity.

FAQ
How Fast Is Terminal Velocity In FPS?
For a 170-pound person wearing two parachutes and using a stable spread position, Emrich calculates that the terminal velocity (i.e, the maximum speed) would be 176 feet per second, or about 120 miles per hour.
Can Humans Survive Terminal Velocity?
People have survived terminal velocity falls. In 1972, Vesna Vulović fell over 33,330 ft without a parachute after the plane she was in exploded. She didn’t exactly walk away from the fall, however. She spent days in a coma, and was hospitalized for months after that.
Can A Rat Survive Terminal Velocity?
A rat can fall as far as 50 feet and land unharmed – in theory! This is not a result found by live experiments, but by calculating the terminal velocity of an average rat at sea-level on Earth. Terminal velocity for animals is approximately 90 d0.
Is There A Maximum Speed For Falling?
Near the surface of the Earth, an object in free fall in a vacuum will accelerate at approximately 9.8 m/s2, independent of its mass. With air resistance acting on an object that has been dropped, the object will eventually reach a terminal velocity, which is around 53 m/s (190 km/h or 118 mph) for a human skydiver.
How Fast Is Terminal Velocity In Feet Per Second?
Based on wind resistance, for example, the terminal speed of a skydiver in a belly-to-earth (i.e., face down) free fall position is about 55 m/s (180 ft/s).
Why Do Heavier Skydivers Fall Faster?
The weight of the skydiver pushes back against the drag force, until the two forces become equal and a constant (terminal) velocity is reached. The heavier you are, the harder your body pushes back against that drag force — and the faster your terminal velocity will be.
Conclusion
In this article, you have learned about what is the maximum speed of terminal velocity in detail. Terminal velocity is the steady speed achieved by an object freely falling through a gas or liquid. A typical velocity for a parachutist who delays opening the chute is about 150 miles per hour. Raindrops fall at a much lower terminal velocity, and a mist of tiny oil droplets settles at an exceedingly small terminal velocity. Once the terminal velocity is achieved the speed of a moving object is no longer increasing or decreasing. So, this was all about the speed of terminal velocity.
