what force is increased after the skydiver open parachute?

Answer 1

To start with there is gravitational attraction. As soon as the skydiver starts falling, (s)he will experience the drag force due to air resistance. The gravitational force is essentially constant but the drag increases as the diver's velocity increases until it equals gravity. The diver is the falling at terminal velocity and will continue to do so until the parachute is operated.

Answer 2

The force of gravity on the skydiver will basically not change over time.Frictional forces (air resistance) will increase as the skydiver's speed goes up.

Both the speed and the air resistance will increase, until the force of air resistance balances the force of gravity. At that point, the skydiver is said to have achieved terminal velocity.

Answer 3

Terminal velocity. I'm pretty sure that's what your asking.
