Broom - a machine

BROOM
Dirty floors!! They're such a hassle so you wanna buy an expensive machine to clean (eg. vacuum)? There's a way easier solution that's cheaper and is surprisingly a machine that goes unnoticed.


A machine is something that has a force applied to it such as, pull, push, levers, etc. That even makes a broom a machine. The fulcrum of a broom that you are using would be the hand you're using closest to the ground. Your top hand then operates the lever that pivots about your bottom hand.


The bristles of the broom is actually another example of a different simple machine. Each bristle acts as a spring when it bends it wants to return to its original form. The bristles at the end of the broom are typically made of straw, hair, plastic, etc. A broom is a great help in life but it’s starting to be replaced by high-tech vacuums. A broom is a daily help in life and way lighter, easier, uses less power, and isn’t loud!!

Don't waste money. Just get something simple.

Sexologist

Just like a biologist, they study biology, a sexologist studies sexuality. Sexology is a scientific study of human sexuality such as psychosexual interactions, sexual interests, behaviour, and functions. Sexology encompasses many different fields such as biology, psychology, medicine, gender studies and much more. There are actually many careers in the sexology topic such as research, sexual education or even counselling. Most issues sexologists have to deal with is the sexual interests in men and woman and their desires. The main point is seeing the transformation of clients and finding out if their sexual interests decrease The vast majority of sexologists did not get degrees in sexology, but rather were trained to study sex within another discipline at the graduate level (e.g., medicine, psychology, anthropology, sociology, etc.).

Forces

These are forces of push and pull motion

High Impact Car Race Results

What did we do?

We had 3 Races.

  • Fastest car race
  • Furthest car race
  • Car that stops closest to the green line
It's pretty simple on how they worked. Which car can go the fastest, which car can stop the furthest, and which car can stop closest to the green line. Everyone had the same car and we had a completely free choice of what materials we wanted to use to improve our vehicle and even what measurement we want our slope to be (mine was 32 degrees) so everyone had a fair choice!

The effects of my modifications

On my car, we used clay and made an aerodynamic based car by putting a sloped on the sides and placing a spoiler on the back. This made it go really fast but not quite as far. Either way, I'm still really proud of my model (car no. 5)

The results



These results are based on the furthest car. As you can see the best results is the more obvious one (car no. 7) that has reached more than 4.5 meters! The lowest one was car no.4 who has gotten way below 1.5 meters :( My car was no. 5 and i had quite a low score as i had said on the effects of my modifications.





These results are based on the fastest car. The numbers on the left are in seconds so we are looking for the shortest bar. My group had just gotten 1 second but we were beaten by car no. 6 who had gotten below 1 second!

The physics of car racing

The Physics Of Car Racing:

1. What has been done to make this a 'fair test'?

  • All the cars are the exact same
  • They all have to drive forward
  • We all have a selection of choice of what materials we want on the car.


2. What forces are needed to make the car go faster
and now have you modified your car accordingly?

We need to add some weight (eg. a stone) on the front to make thrust (creates acceleration). If we add it to the back it will spin around and fail the race.

3. What forces are needed to make the car stop and
what adjustments have you made to try & stop it by the line?

Add something such as a parachute to create drag (attempts slowing the car down) and Friction (stops the car).

4. What forces are needed to make the car travel further
and what adjustments have you made to achieve this?

A balanced force; if something is NOT moving it will continue to not move; if something IS moving it will continue to move at the same speed and in the same direction.

Song cover

Ed sheeran - castle on the hill (COVER)
I love how he put a lot of effort into this and his vocals are really great and in tune with the guitar.

Physics of car racing

What i tried today - why i tried it?
Today Xij and I did some random experimenting and we had this triangular shape out of sticks and we used clay to stick it on the top of our car and it went really well as it went really fast and straight.

What happened when i tried to race it?
Well as i said before it went really fast and straight! The only thing is that we aren't sure how to make it stop yet.

What will i try next time?
Next time I'm gonna try figure out some ways and experiment to make it stop.

What research did I do?
Xij did most of the researching so I'm not quite sure what we looked at
