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.

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

Cars

1. What problems does our car already have?

The problem is our car spins around.

- what is causing the problem?

The weight on the back of the car.

- how do you plan to correct it?

Add more weight on the front.

2. How do you think you will make your car go faster?

Making an aerodynamic design.

3. How do you think you will slow your car down?

Placing sandpaper at the end.

4. What equipment do we need?

• Paper
• Scissors
• Tape
• Playdough

Music

The song I am going to learn is Castle On The Hill
Ed Sheeran composed the song
Ed Sheeran performed the song
The song is about his hometown and his days of growing up in his childhood

Tug o war - Friction

What can we play tug o war on that has more friction?

Carpet - I think carpet is a good surface because the carpet is fluffy so there's more friction
Concrete - It got 50/50 friction depending on what's on your feet but I don't think it's the best place to play.
grass - the grass has less friction because it's muddy and slippery so everyone will slip.
Lino - this one has maybe quite a bit of friction not that bad for slipping

I found out that for me I found the concrete easiest and the carpet wasn't bad it was just painful on my hands. The hardest was the grass cause my feet kept on moving in the mud even when I was standing in a statue position. The lino was correct for me because i had one moment that i kind of struggle staying in one place but it was all good.
