We had a cart, ticker tape, 100g weights, and were asked to test out various scenerios with regards to force and mass, hence acceleration.

Newton's lab results
On Friday, I overcame my fears of car crashes, ticker tape, and pulleys, and tested out Newton's laws.
We had a cart, ticker tape, 100g weights, and were asked to test out various scenerios with regards to force and mass, hence acceleration.
I have to double check the results, i'm not entirely sold on mine...

Building our tallest structure
Using Newton's law, we were asked to build our own tallest structure.
Our own tallest structure conveyed great height...yet it wasn't enough to overcome the concept of standing.
As you can see in the picture below, although the tower had enough height, it required Patrick to support it as we took our group picture.
The reason why we believe our tower didn't stand is simple; our base was too light. If we'd had a stronger base, possibly one that was filled instead of hollow, I believe that our structure would've had a good chance of standing against gravity.
Also, extra support along the sides acting as wire to bind the tower to the ground would've been useful, although illegal, under Mr. Chung's rules.

5 types of projectile motion
Is it just me or does blogger make simple tasks complicated?
I'll rotate and space these beautifully after I do my blogger tutorial. Regardless, here's proof I did my homework :)

The Tallest Building in the world
As of 2011, many booming skyscrapers stand on God's green Earth, but I only need to discuss one, feel free to google the rest. :)
The Burj Khalifa (Khalifa tower) is a free standing superskyscraper in Dubai, finished as of 2008. The tower, boasting over 828m tall, consists of 160 stories used for permanent and temporary residence, observation decks, conference rooms, suites, and lobbies.
To build the tallest tower possible with paper and tape, the plan would to probably be to roll the paper into cylinder shapes as support, and then to make the cylinders narrower as we go up the structure. That's our plan, wish us luck.
