A hail stone of 1 centimetre (0.39 in) in diameter falls at a rate of 9 metres per second (20 mph), while stones the size of 8 centimetres (3.1 in) in diameter fall at a rate of 48 metres per second (110 mph). At terminal velocity: D = W Cd * r * V ^2 * A / 2 = W Solving for the vertical velocity V, we obtain the equation V = sqrt ( (2 * W) / (Cd * r * A) So, let’s say you’re a skydiver jumping out of an airplane. Terminal Velocity On The Moon. speed of sound,
Viewed 312 times 0 $\begingroup$ Im not so sure about why a body has a terminal velocity. Can a falling body on earth exceed its terminal velocity in a huge vacuum container? The value of the terminal velocity depends not only on the planet in question, but also the body that’s falling: for example, its cross-section, its coefficient of drag, its mass, etc. Terminal velocity on Earth is roughly 120 mph, yet we know objects in space, such as planets, move far faster than that due to gravitational attraction towards each other. The two main factors that dictate an object’s terminal velocity on Earth are its weight and surface area, with heavier, small surface area objects having a greater velocity. When an object (like a skydiver) falls freely through a medium, such as water or air, the force of gravity pulls it toward Earth. But they can increase their speed tremendously by orienting their head towards the Earth – diving towards the ground. Terminal Velocity In the Round Earth model, terminal velocity happens when the acceleration due to gravity is equal to the acceleration due to drag.
