The force that changes is air resistance and the force that stay the same is gravity.
The force that changes when a sky diver's parachute opens is air resistance.
air resistance changes. But gravity stays the same.
When the parachute opens gravity stays the same. The force that changes is the air resistance. Air resistance is usually calculated using the drag calculation.
Air resistance increases.
The force down remains constant.force down (newtons) = (mass (kg) * acceleration due to gravity ((m/s)/s) ).The force up varies with velocity and drag coefficient ( which increases significantly when the chute opens).force up (newtons) = velocity2 * drag coefficient

Gravity doesn't change.
Sky divers do not go up, but they do undergo deceleration due to the increased drag incurred by the parachute being suddenly opened. Since skydivers, when being filmed by a cameraman, release their parachute first, there is a relative acceleration between the cameraman and the skydiver, creating the illusion that the skydiver is travelling up.
-- The force of gravity is unchanged before and after.-- The force of air resistance on the skydiver is greater before, and less after,because she is falling slower after the parachute opens.-- The effect on her of air resistance is greater after the parachute is open. Theincreased air resistance itself acts on the parachute, and its effect is transferredto the skydiver through her harness.

Air resistance will increase when the parachute opens, and the decent of the skydiver will slow down.
At terminal velocity (forces balanced): drag coefficient changes when chute is opened, increasing drag force , net force is upward, deceleration takes place to new (lower) terminal velocity.
