Jun 22, 2022 · What is the Terminal Velocity of a Human? When a skydiver jumps from a plane, his velocity increases due to acceleration due to gravity. However, since he is falling through air he experiences drag force due to air resistance.

We all know that when an object is released from a certain height, it starts to fall. This, of course, is due to gravity, or more specifically, the gravitational force of attraction between the object and the Earth. The force of gravity causes the object to accelerate and increase in velocity as it falls downwards towards the Earth. In actuality, b...
Before we go any further, let's define some of the terms used in kinematics,which is an area of physics concerned with the motion of objects. 1. Mass: the amount of matter in an object. The greater the mass of an object, the greater the amount of inertia it has and its reluctance to move. 2. Speed:the rate of change of position of an object (how fa...
If an object falls in a vacuum outside Earth's atmosphere, its velocity continues to increase because of the acceleration due to gravity. This is called free fall. However, if the object falls through the air (or another fluid such as water), this limits the maximum velocity it can reach.
When an object moves through a fluid, it experiences a force which opposes motion and tends to slow it down. This force is called drag. The fluid could be a liquid, such as water, or a mixture of gasses, such as air. If you put your hand out the window of a moving car or try to wade through water, you can feel this force.
Mass is the amount of matter in a body, but in physics, mass and weight have very specific meanings. While the mass of an object is the same, irrespective of where it is located in the Universe, weight varies. Weight is the gravitational force between objects and equals mass multiplied by the acceleration due to gravity g. So the force of gravity o...
The net force acting on a free-falling body is the difference between the weight acting down and the drag force acting upwards. As long as this is positive, the body keeps accelerating downwards. Since the drag force increases with velocity, eventually at some stage it equals the weight of the falling body (which isn't changing and stays constant a...
As an aside, let's look at the equation for the velocity of a falling object when there's no drag. If an object falls through a vacuum without being slowed down by a drag force, its velocity v in m/s is given by the equation: where g is the acceleration due to gravity. and h is the distance fallen in metres (m) In terms of time t in seconds since t...
The drag equation describes the force experienced by an object moving through a fluid: If Fdis the drag force, then: Where Fdis the force in newtons (N) p is the density of the fluid in kilograms per cubic metre (kg/m3) uis the velocity of the object relative to the fluid in metres per second (m/s) Cdis the drag coefficient that depends on the shap...
At equilibrium, the drag force Fd acting upwards equals the weight Fg acting downwards We know Fd= ½ ρ u2 CdA and Fg= mg At equilibrium, the velocity becomes the terminal velocity. Let's call it Vt Equate Fg to Fd and replace u by Vtgiving: mg = ½ ρ u2 CdA = ½ ρ Vt2 CdA So: 2mg = ρ Vt2 CdA Divide both sides by ρ CdA giving: 2mg / ρ CdA = Vt2 Taking...
From the equation for terminal velocity, we see it depends on several factors: 1. Density of the air 2. Mass of the object 3. Area of the object 4. Acceleration due to gravity (this doesn't really change, so it can be assumed to be practically constant) 5. The shape of the object For a human, the drag coefficient Cdis about 1 in a belly down, horiz...
