When a skydiver opens the parachute, he or she does not move upward, but rather, continues to move downward, but at a slower speed. Sometimes there is an illusion that the skydiver is moving upward, because if there are several people skydiving together, and one of them opens a parachute while the others don't, you will see the skydiver with the open parachute moving upward with relation to the other skydivers. But they are all still moving downward, they are just doing so at different speeds.

When a skydiver falls the air is forced to move around him. What energy transformation does this cause?

As the skydiver falls, the moving air around them causes the conversion of the skydiver's gravitational potential energy into kinetic energy. This is because the air resistance exerts a force on the skydiver, causing work to be done and energy to be transferred from potential to kinetic.


Why is gravity important for skydiving?

Without gravity, there would be no atmosphere to skydive in (or breathe!). All the air would simply disperse into space. The pull of gravity gets weaker, the further you are from the Earth, however this is not noticeable by a skydiver jumping from 15,000ft. Gravity helps the air to stay close to the earth. This air can be manipulated to turn, move forwards & backwards, increase and decrease freefall speeds, remain stable and of course help to deploy the parachute. So yes gravity is vitally important to skydiving and life.


Can a pulley move a load side ways and upwards?

Yes, a pulley can move a load both sideways and upwards with the use of multiple pulleys and appropriate rigging configurations. By adjusting the angle of the pulleys and the direction of the force applied, it is possible to move a load in various directions using a pulley system.


What happens to a moving object with zero nets force acting on it?

Certainly. Say you have an object that has been falling through the air for a long time, say a skydiver. After falling for a long time, the skydiver will fall at a constant velocity. This is called terminal velocity, and this is when the air resistance pushing up around the skydiver is equal to the force of gravity pulling the skydiver down. The skydiver is not accelerating. By using F= ma, with zero acceleration, there is zero net force. The skydiver is moving as if there are no forces acting on the skydiver.


How do you move the cursor up and down?

You can move the cursor up and down by using the arrow keys on your keyboard. Press the up arrow key to move the cursor upwards and the down arrow key to move the cursor downwards.

The motion of the parachutist after he pulled his rip cord made him appear to be moving upward?

Skydivers do NOT move upwards at all when we open our parachutes. We don't even bounce a little. That is an illusion caused by the camera operator still falling at full speed while the first jumper opens their parachute and slows. Now, it is possible to move upwards in some limited circumstances. When exiting a fast-moving aircraft while wearing a wingsuit, you can rise above the plane for a (very) short time. Also, once your parachute is open, you can flare your canopy enough to slightly (by a few feet) gain altitude.


What happens immediately after skydiver opens her parachute?

When her parachute opens, the air resistance increases. Now there is a resultant force going upwards on the parachute. The increase in air resistance occurs because when the parachute is opened there is a much larger surface area (than before) so the particles of air are much more likely to get 'caught up' in the parachute unable to pass easily, therefore creating more air resistance (an upwards force) and so slowing down the parachutist. NOTE: The parachutist does NOT move upwards after the parachute has opened, they just slow down. This effect comes from when a parachutist with a camera is filming opposite, they are still falling rapidly while the other person's parachute has opened, therefore passing them as they continue to freefall, and so the parachutist opposite appears to move upwards after opening the parachute.


Why is a skydiver not in freefall?

A skydiver is not in freefall when they have opened their parachute. The move from free-fall to controlled decent under a wing.

What forces act on a skydiver as they are diving?

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.
