when a skydiver jumps out of a plane, the dominant force is gravity, pulling him/her towards the ground, although some air resistance is also acting on him/her, allowing him/her to fall at a steady speed (not dropping like a stone), so the forces acting on the skydiver are almost balanced. of course, all that changes when the parachute opens. then the air resistance greatly increases, drastically slowing the descent down to earth.
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 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.

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.
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.

When the forces due to gravity and air resistance balance each other, the skydiver reaches terminal velocity. At this point, the skydiver falls at a constant speed and experiences no further acceleration. This allows for a safer and more controlled descent to the ground.
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.
