The speed of a falling parachutist is around 120 mph (193 km/h) when the parachute is fully deployed. This speed allows the parachutist to descend safely and land without harm.
When a parachutist reaches terminal speed, the force of air resistance pushing up on the parachutist equals the force of gravity pulling the parachutist downward. At this point, the net force on the parachutist is zero, resulting in a constant velocity.
A parachutist falling before opening the parachute experiences an acceleration due to gravity of approximately 9.81 m/s^2, which is the acceleration due to free fall. This acceleration causes the parachutist's velocity to increase as they fall towards the ground.
When a parachutist is falling, potential energy from height is converted into kinetic energy as the parachutist accelerates towards the ground. As the parachute is deployed and air resistance increases, some of the kinetic energy is converted back into potential energy, slowing the fall.
Gravity is pulling the parachutist downwards towards the Earth, while air resistance (or drag) is pushing upwards against the parachutist's fall, slowing down their descent.
When a parachutist is falling, the forces acting on them are gravity pulling them downward and air resistance pushing against their fall. Gravity is the dominant force causing the parachutist to accelerate towards the ground while air resistance counteracts this force, eventually leading to a terminal velocity where the forces are balanced.
There are two possibilities. One is that he is falling at a constant (positive) speed. In this case, the downward force of gravity is exactly offset by the upward force of drag or air resistance. The parachutist is said to have reached terminal velocity. The second possibility is that he is moving downwards at a constant speed of zero. He has hit the ground! The parachutist may be said to have reached a terminal situation!

No. When you see a video of a parachutist "moving up" it is because the person with the camera is falling faster than the person they are filming.

The falling of a parachutist without his parachute deployed will be quite fast. We can slow his decsent by putting a drag on the free fall with a parachute. The fall is no longer free of drag (friction).
When a parachutist jumps, the parachute deploys and opens up, creating a large surface area. This increases air resistance, which slows down the fall by creating a drag force that counters gravity. The parachute allows the parachutist to safely land at a slower speed than if they were falling freely.
Air resistance, also known as drag, affects the way a parachutist falls by slowing down their descent. As the parachutist falls, the force of air resistance increases with speed, eventually reaching a point where it equals the force of gravity pulling the parachutist down. This creates a situation known as terminal velocity, where the parachutist falls at a constant speed without accelerating further.
It is air resistance which slows the rate at which a parachutist falls, turning what would otherwise be a fatal fall into a controlled landing.
