When the crumpled and not crumoled tissues are dropped, the crumpled one falls faster because the non-crumpled one has wind push under it so it slowly falls down while the crumpled tissue can't have wind pushing under because of the shape ======

==== In April on the 28th in 1995 at Cave creek/paparoa National park there were 14 deaths of the public when the accident of the look out platform that was about 30m high collapsed.It collapsed because of the stucture how it was designed and built, it was obviously not strong enough to hold up that mass of people at that time. The people were stronger together than the platform. ==== ==== ﻿on April the 28th 1995 17 young people from an outdoor recreation course and a conservation officer fell from a 30 metre platform into a crevas .14 of those young people and the conservation officer died, 3 people were injured some with intensive injuries. the people who created the platform in 1994 were not official engineers or designers so they did not have the right qualifications.As they were not qualified for the job the platform became unbalanced and with the mass this caused itself to dislodge. ==== ==== On the 28th of April 1995 17 students from the outdoor recreation course at Tai Poutini polytechnic crowded into a viewing platform high above cave creek the platform collapsed and fell about 30 meters. 14 people lost their lives and 4 others were left injured. 13 students and a department of conservation field officer died. gravity would of had an effect on the viewing platform because of to much mass being applied on to the viewing platform at one time.

The car going down the slopped ramp will go faster on the deck because theres less friction and it has less friction because of the matirial used to make it, and as you know wood is quite smooth. The car didn't go as fast as it did on the carpet as it did on the deck because of the materials used to make it carpet has alot of friction and is quite rough, but did you know what also helps it roll along stuff so well is the shape of the weels they are spares and they roll very good on flat surfaces. By Chantelle How we could stop cave creek incident!!!

The cave creek incident was a horrendous uncommon event. Cave creek caused many deaths and injuries.

Cave creek was a platform built so people could view the Cave creeks chasm and headwaters

On April twenty eighth nineteen ninety five a group of students and tutors from the outdoor recreation course at Taipoutini.as the party walked Into the bush they split into two Groups.the larger group of eighteen including the punakiki Field centre officer,reached the viewing platform first.at Eleven twenty five am the larger group moved onto the platform

By Max
It tipped over off it's base and fell onto the boulders and rocks Of the creek bed below taking the victims with it. A student Went and got help.

The cave creek incident was tremendously terrible incident That caused plentiful deaths and injuries we could have pre Vented this by building the structure of the platform stronger by Making it like an arch bridge with a flat platform onto so there is Equal tension and compression to make it balanced.if This hadn't have happened these students would still be alive. This is for number 4 this balloon is spining the coin inside it which makes spin around and use centripial force its like the wall of deatn if it suddently stopped it would fall straight down. By Erin When the car goes down the sloped ramp on carpet the car stops quicker then on the deck.This is because of many things .The force from the slope and the smoothness of the the deck make the car go down the ramp and keep going for longer.When the car is going on the carpet its stops quicker because the surface of the carpet is alot more rough and bumpy.There for when the car is going down the force gets stopped because of the roughness of the carpet BY SOPH Photo two they put the marbles under the lid cause when you push off the wall You move backwards because the wall is bigger than you so it sends a stronger force back at you And you also throw the ball and it will send a force back at you. By devos When the bucket is swung around the water inside is using centripcal force to stay in the bottom of the bucket byREUBEN:)!! when the marbale spins in the ballon the marbale uses centripical force to stay on the sides by connor

when the marbale spins in the ballon the marbale uses centirpical force to stay on the sides by bradon when the bucket has been swung around with force the cintripical force engages it to stay in the bucket without it falling out. BY BRITTANY

when they drop the paper and the crumpled paper would hit the ground because of gravity and the crumpled papers size diifrents and because it has more mass so it will hit the ground before the not crumpled paper does BLAKE ROXXXXX !!!!!!!!!!!!======

﻿when bradley pulled the tablecloth from under the lunch box the force inertia was applied to the table cloth but not the lunch box causing it to quickly ettract from beneath it but unfortunately this did not work in bradleys case instead the lunchbox went flying with the table cloth it may have worked if bradley had done it a little bit faster but oh well !!! ======

When the bucket swung around the person was using force from there arm. And the water was staying in because of the cintripical ﻿force. By DILRAJ ======

= when the bucket is spun around and the person is holding the bucket using his arm force to spin it around and that is called cintripical force.By Max = = when the table cloth slides out from under the 2 bottles the whight of the bottles slowes it down.BY BRADLEY = = = = Number 3 when Toni blows through the tube the paper will stay but if she sucks the tube the paper will go up with the tube =
 * Newtons Laws **
 * I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. **


 * II. The relationship between an object's mass //m//, its acceleration a, and the applied force //F// is //F = ma//. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector. **


 * III. For every action there is an equal and opposite reaction. **
