What are the forces acting on a skydiver?
The main forces acting on a skydiver are gravity, which pulls the skydiver downward, and air resistance (drag), which acts in the opposite direction of motion. As the skydiver falls, air resistance increases until it balances out the force of gravity, leading to a constant velocity known as terminal velocity.
What is the drag coefficient for a rock?
The drag coefficient for a rock can vary based on its shape, size, and surface texture. Generally, rocks have a drag coefficient ranging from 1.0 to 3.0, depending on these factors. Smoother, more streamlined rocks will have a lower drag coefficient compared to rough, irregularly shaped rocks.
When a sky diver reaches terminal velocity what happens to the two forces of weight and drag?
When a skydiver reaches terminal velocity, the force of weight acting downwards on the skydiver is equal to the force of drag acting upwards. This means that there is no net force acting on the skydiver, resulting in a constant velocity rather than acceleration.
What forces work on a skydiver?
(standard air pressure and gravity)>(Constant) Force down (newtons) = mass * acceleration due to gravity>Say 70 kg skydiver @ 9.82 m/s/s = 70 * 9.82 = 687.4 newtons>Force up (newtons) = velocity 2 * drag coefficient (say 0.16 typical)>Terminal velocity (when forces balance) 687.4 = v 2 * 0.16Terminal velocity = square root (687.4 / 0.16)= 65.546 metres per second ( 147 mph) terminal velocity
Why does a skydiver loose speed when he opens his parachute?
A skydiver loses speed when he opens the parachute because the parachute creates drag by slowing down the movement of air. This drag force opposes the motion of the skydiver, causing a decrease in speed. Additionally, the larger surface area of the parachute increases the effect of air resistance on the skydiver's body.

What is the drag coefficient of the 2015 Nissan GT-R?
The 2012 Nissan GT-R has a drag coefficient of 0.26 Cd.
Relationship between coefficient lift and coefficient drag?
For cylinders coefficient of lift is approximately half of coefficient of drag while they are equal for Aerofoils.
