What force changes when a sky diver's parachute opens what force stays the same?

Air resistance (drag) increases massively as the parachute opens, far exceeding the jumper's weight. The force of the jumper's weight and his equipment remains the same.


Forces of attraction between molecules of the same kind are called what?

Forces of attraction between molecules of the same kind are called COHESIVE FORCE.


What is the difference between cohesive forces and adhesive forces?

Cohesive is forces within the same material (same molecules). Adhesive is the force between two different materials (two surfaces of different molecules).


What are the differences between balanced forces and action and reaction forces?

Balanced forces means that the sum of forces on an object is zero. There is no guarantee that forces are always balanced. If forces are unbalanced, the object will accelerate. This is related to Newton's Second Law.Action and reaction forces refer to Newton's Third Law. If an object "A" pushes against an object "B", object "B" will push back on object "A" - with a force that has the same magnitude, but in different directions. The two forces, in this case, are on different objects. Balanced or unbalanced forces, in the previous paragraph, refer to forces on the same object.


How do unbalanced forces act on an object?

If forces on an object are unbalanced, the object will accelerate or decelerate. If forces on an object are balanced, the object will stay still or keep moving with the same velocity.

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


What is the name of the force that changes when the parachute opens?

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.

Does a parachute go up when opened?

No. A parachute is falling when it opens. It simply falls less quickly. ** If you are asking this because you think you have seen it happen on TV, the illusion of the parachute going up when opened is because whilst diving without 'chutes, the cameraman and the other skydiver are falling at the same speed, but when the guy in the frame opens the chute he falls at a slower speed than the camera man. So the camera man falling faster gets further down than the other guy. Thus creating the illusion.


What force changes when a sky divers parachute opens?

air resistance changes. But gravity stays the same.


What force changes when a sky diver's parachute opens?

The force that changes is air resistance and the force that stay the same is gravity.

What happens immediately after a sky diver opens his parachute?

Once a skydiver deploys his pilot chute, the drag created pulls the closing pin (attached to the bridle) and the deployment bag, containing the main canopy, is released. As the deployment bag is pulled upward, the lines are released from their rubber band stowes, which opens the deployment bag and exposes the main canopy. There is a rectangular slider made of the same parachute material as the canopy that slides down from the canopy to the risers that attach the canopy lines to the container (and thus to the skydiver). This ensures a slow, controlled canopy opening and a safe reduction in fall rate from terminal velocity to a much slower speed. The main canopy is fully deployed when the canopy is square (rectangular, actually) and the slider is all the way down and touching the risers. Now, after a controlability check, the skydiver is able to maneuver his canopy and make a safe, soft landing.


When you pull a cord on parachute do you go back up?

You do go up, relative to the cameraman, but you never actually gain altitude. When the parachute opens you accelerate upwards and you fell exactly the same as if you were accelerated upwards from rest.

Which is better a small parachute or a small parachute?

They are exactly the same!


How can a skier achieve greater velocity than a skydiver?

If a skier is in a jump, then a skier and skydiver is pretty much the same thing. In general though, a skydiver has only air resistance, the skier has air resistance and friction with the ski-snow, so the skydiver has an edge on speed.
