Elastics Around The Egg example essay topic

Newtons first Law: An object will remain at rest, or in motion, unless acted on by a force. Newtons second Law: Force = mass over acceleration Newton's first and second law has an important connection to the egg mobile assessment task. Newton's first law tells us that an object will remain at rest or in motion unless acted on by a force. In the experiment, a box of some sort will be dropped 3 metres in hight with a raw egg inside.

There are limited resources that can be used ie: Paper Cardboard Polystyrene Plastic Rubber Matches Wood Drinking straws String Cotton Rubber bands Sticky tape Glue With these resources, I have to make a mobile vehicle that is safe for the egg to be dropped without breaking. To use Newton's first law to protect my egg I will use elastic bands, wood, and a cardboard box to save my egg from breaking. The elastic bands will hold the egg in the middle of the cardboard box - the egg not touching any walls. Cotton balls will be all around the egg to protect it when the box hits the ground with force. The egg should bounce a fraction but the cotton ball should soften the bounce and save the egg from breaking. Newtons second law will help me because if the force equals mass over acceleration, I know that the lighter my experiment is, the slower it will fall.

Sir Isaac Newton: Sir Isaac Newton was born on the 25th of January 1642 in Wools thorpe Lincolnshire, England. His father was a farmer but died 3 months before Isaac was born. His mother remarried a wealthy elderly clergyman from the next village when Isaac was three. She went and lived with the man in the other village leaving Isaac in his grandmother's hands.

He was picked a scholar, guaranteeing him four years of financial support in 1664. The plague was spreading through Europe at that time and reached Cambridge in summer 1665. Newton returned home for two years where he concentrated on problems in physics and mathematics as the University closed. In 1684, Newton's opponent Robert Hooke meet up with two members of the Royal society and as Hooke bragged about how he knew the laws controlling the motion of the heavenly bodies, one of the members was not satisfied with his explanation.

Christopher Wren h offered a prize to anyone whom could solve the puzzle. Edmond Halley, the other member, was a friend of Newton's, who took the problem to him. Halley asked how the planets would move if there was a force of attraction between bodies that weakened as the square of the distance... Halley was astonished when Newton answered straight away saying "in ellipses". Halley asked in disbelief how he knew that. Newton answered simply " l have calculated it".

Newton then told Halley all of what he had learnt throughout the years where the plague has forced him to stay in the country. Halley then pursued Newton to write a book - which he did. It was called Philosophiae Principia Mathematica. In 1669 Newton became a professor of mathematics. In early 1672 Newton was elected to the Royal society.

He published a book " Principia Mathematica" in 1687 that demonstrated his laws of motion and theories of gravitation. Much happened for the next 40 years, some including being a Member of Parliament served of master of mint, publishing his theory of light, but on March 20th 1727 Newton died at the age of 85. Problems - solutions 1 The first problem that occurred was that the egg broke! It broke because there wasn't enough support for the egg and either did any of the other things I planed for its safety. I then decided to make a new sort of vehicle. My first vehicle that failed: It failed because when the vehicle hit the ground, the egg wasn't protected enough.

Next time I will protect it more My second vehicle that failed: This failed because the egg kept falling out of the elastic bands. It did this because there wasn't enough friction to hold the egg still. My third vehicle succeeded: This vehicle succeeded because the egg couldn't move and therefore was saved from breaking. I put elastics around the egg as well as to hold it up. Another one of the problems I had with my vehicle was it broke. It was a shoebox (made out of cardboard).

The problem was that my elastics where too tight and caused the box to cave in. Because my shoebox had completely broken I had to think of a new box I could use that would be stronger and dependable. My solution was to use a flower box - which was a lot thicker and stronger. My other problem was that the egg would still move too much while being held by the elastics. My solution was to place elastic around the egg so when it tried to move the elastic holding it in the box would stop it. This is because when the egg tried to mover the elastic bands rubbed up against the other bands creating friction, which held the egg in place.
