When the skydiver jumps out of the plane without releasing the parachute, the speed increases until a certain speed that will remain constant before the skydiver release the parachute due to gravitational force acting on the skydiver. Once the skydiver releases the parachute, The speed of the Skydiver would decrease as frictional force( air resistance) is acting in the direction against the parachute as friction opposes motion. This helps the parachutist from falling to the ground at a high speed which prevents her from dying.  ]]> 2018-07-31 06:26:29 UTC https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528642 ew https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528646 2018-07-31 06:26:34 UTC https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528646 Ryan + Keithy Boi https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528648 1. counter force exerted by the floor of plane until skydiver leaves plane.
2. Once out of plane, skydiver accelerates rapidly downwards  due to gravity.
3.As Skydiver accelerates, air resistance builds up and becomes greater until it matches the gravitational pull of earth.
This makes the skydiver fall downwards at a constant speed.
4.When the skydiver opens the parachute, air resistance becomes greater than t he gravitational pull and the skydivers speed decreases rapidly.
5.When the skydiver reaches the ground, a counter force will be exerted by the ground and the skydiver will stop falling downwards almost instantly.

On the aeroplane/airplane, the upward lift of the airplane counters the downward force of gravity, causing the skydivers to not fall.

The skydiver's weight is constant throughout the fall. 

Air resistance (friction) slows the skydiver down, causing the skydiver to go at a constant speed downwards.

As the skydiver is about to land, a parachute is deployed, which significantly increases the amount of air resistance of the skydiver, slowing the skydiver down enough such that the skydiver does not kill himself.

 We also noticed that the parachute helped to stop her from ending up as a great red splat of ketchup on the face of the Earth by helping to increase her air resistance and slowing down her speed. ]]> 2018-07-31 06:26:49 UTC https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528663 Ming Kai & Val https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528668 The gravity pull the skydivers towards the Earth.When they want to slow down,the upwards force must be greater than the downwards force,known as gravity.When they slow down,balance is achieved.The faster the fall,the greater the gravity]]> 2018-07-31 06:26:54 UTC https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528668 Venedict and Yung Zhao https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528675 The gravitational force of the earth is being balanced out by the plane's direction of upward movement. When the skydiver jumps off the plane, gravity is the only force working on the skydiver and she slowly gains speed. After some time, she is falling at a constant speed. Her speed then slows down when she releases her parachute as the parachute has a large surface area which increases air resistance. This air resistance counters the gravitational pull, balancing out the upward and downward forces.]]> 2018-07-31 06:27:04 UTC https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528675 https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528687 2018-07-31 06:27:17 UTC https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528687 https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528700 2018-07-31 06:27:24 UTC https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528700 evonne & yuxi https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528719 the force of gravity constantly pulls us towards the earth. air resistance is acting in the opposite direction, the faster she falls, the greater the air resistance. eventually, the upwards force of air is equals to the downward force of gravity and the speed remains constant as the forces are balanced. it does not mean that she stopped falling, it just meant that she stopped accelerating.]]> 2018-07-31 06:27:41 UTC https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528719 Mabel & Priya https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528722 The faster the sky diver falls to the ground, the more the air resistance.  The skydiver uses a parachute  to increase the air resistance that acts on her to slow her down.

the floor of the plane is a counter force 

when gravity pulls her down she starts to accelerate

the faster she falls the greater the air resistance

the gravity and air resistance is balanced so her speed is constant

when parachute opens the air resistance is greater than gravity n so the forces are imbalanced and she slows down reaching a slower constant speed

this shows that air resistance and gravity will change depending on the other force.

After  a while, the downward force of gravity balances with the upward force to balance the skydiver when she is falling. To slow down, the upward force needs to be greater than the downward force. The skydiver will then release the parachute. Air resistance takes over the downward force of gravity and she lands to the ground slowly. :)]]> 2018-07-31 06:28:09 UTC https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528745 Xinjie & Sherilyn https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528758 When a skydiver jumps out of a plane at 3000m her speed goes through some big changes. The force of gravity is always trying to pull us towards the earth. Before the skydiver jumps, the floor of a plane provides a counter force which balances the downward force of gravity right until the moment the skydiver steps out of the plane. Gravity immediately pulls her to the ground and she starts to accelerate downwards. Air resistance is acting in the opposite direction the faster she falls. the greater the air resistance. Eventually, the upward force of the air equals to the downward force of gravity. when forces are balanced the speed will remain constant.]]> 2018-07-31 06:28:21 UTC https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528758 Peng Gin & Xing Yu https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528770 When the skydiver was on the plane, the gravitational force and counter-force are equal. When the skydiver jumps off, there is air resistance but the air resistance is smaller than the gravitational force so the skydiver will accelerate as he falls down. After a while, the air resistance will become equal with the gravitational force and the skydiver will fall at a constant speed. When the skydiver deploy his parachute, the air resistance will become bigger and he will slow down as the air resistance becomes equal with the gravitational force. ]]> 2018-07-31 06:28:33 UTC https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528770 Jia Wen & Raen https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528798 The skydiver falls as there is gravitational force acting on him. When the skydiver falls out of the plane, the faster he falls,  the greater the air-resistance. ]]> 2018-07-31 06:29:01 UTC https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528798 jolie and joy https://padlet.com/enen_janggeum/43lquu85v00u/wish/271528902 forces change as the skydiver jumps from the plane until he reaches the ground

gravitational force is acting on the skydiver all the way for example the when skydiver is on the plane.

The higher the skydiver is, the more the gravitational force, which pulls the skydiver down. After she releases the parachute , she slows down as the parachute has a large surface area which allows air to push it up, also slowing down the skydiver. ;]]> 2018-08-01 04:15:54 UTC https://padlet.com/enen_janggeum/43lquu85v00u/wish/271632135 Klien and Rachel https://padlet.com/enen_janggeum/43lquu85v00u/wish/271632690  
The gravity makes her GOTTA GO FAST.
After a while there is more air resistance due to her speed so she's NOT SO FAST.
The girl girl will no longer accelerate then and will move at a CONSTANT FAST. But she will still go SPLAT! if she bangs the ground.
When the girlie opens the parachute, there is more air resistance and she starts to slow down (no longer Sonic). But now she won't SPLAT! when she bangs the ground so she won't DIE DIE DIE!
