(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 * 0.16
Terminal velocity = square root (687.4 / 0.16)
= 65.546 metres per second ( 147 mph) terminal velocity
When a skydiver is accelerating downward, the forces are unbalanced. The force of gravity acting downward on the skydiver is greater than the air resistance force pushing upward, causing the skydiver to accelerate downward.
When a skydiver reaches terminal speed, the air resistance is equal to the force of gravity acting on the skydiver. At this point, the acceleration of the skydiver is zero, as the forces are balanced. This means that the skydiver is falling at a constant speed due to the opposing forces being equal.
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.
Work is the force times distance, so the answer is 2,850,000 joules.
Gravity pulls the skydiver towards the centre of the earth (downwards force). The air causes wind resistance, slowing the sky diver down (upwards force). The wind can also cause a slight sideways force upon the skydiver.

When the two forces acting on the skydiver are balanced, the acceleration is zero. This occurs when the force of gravity pulling the skydiver downward is equal to the air resistance acting upward. At this point, the skydiver reaches terminal velocity, meaning they will continue to fall at a constant speed without accelerating further.
Work is the force times distance, so the answer is 2,850,000 joules.

Gravity pulls the skydiver towards the centre of the earth (downwards force). The air causes wind resistance, slowing the sky diver down (upwards force). The wind can also cause a slight sideways force upon the skydiver.
As the skydiver falls, the air resistance forces kinetic energy to be transformed into thermal energy due to friction between the air and the skydiver's body. This reduces the speed of the skydiver as they fall towards the ground.
As the skydiver falls, the moving air around them causes the conversion of the skydiver's gravitational potential energy into kinetic energy. This is because the air resistance exerts a force on the skydiver, causing work to be done and energy to be transferred from potential to kinetic.
The air resistance on the skydiver at terminal velocity is 500 N. At terminal velocity, the air resistance on the skydiver is equal in magnitude to the gravitational force pulling them downward. This balance of forces results in a constant velocity.
Skydiving involves concepts from Newton's laws of motion, particularly the forces of gravity and air resistance. When a skydiver jumps out of a plane, gravity pulls them towards the Earth, creating acceleration. As the skydiver falls, air resistance pushes upward against gravity, eventually reaching a point where these two forces balance out, leading to a constant terminal velocity. This terminal velocity is the speed at which the forces of gravity and air resistance cancel each other out, allowing the skydiver to fall steadily until reaching the ground.
