ElECTRICITY

Today I Learnt about Electricity .
There Two ways on how electricity Runs chemical or Magnetically
A Car runs on 12.7v And a AA-battery runs on 1.5v Which is not enough to run a TV
Electricity Flows From positive  to negative voltage Flows for Negative to Positive.

PAPER AIR PLANE

The four things you consider when building a paper plane ?

You Should have gravity , Thrust , Drag and lift

The Importance of your wing shape and angle ?
An aerofoil design relies on the Bernoulli effect
to do with air travelling faster over top then underneath

The Importance of weight and balance ? 

If the paper air plane is to heavy it may never be able to fly.
If the air plane is out of balance it would be uncontrollable when it takes
fight and wont fly evenly.


How would you change the design ?
If I had to change the design make sure that the wings are facing up
so that it gets go air flow both on top and underneath

SPACE SUIT

Why is a cooling system necessary ?

Cause when you have all the stuff under neath and on top you

get how really quickly.

How do astronauts deal with sun in there eyes ?

Safety Gloves

Make you have adult supervision

Do not eat or drink your experiment

So it can launch with more energy behind it.

THE DIFFERENCE BETWEEN DIESEL AND PETROL

The biggest difference between diesel and petrol is combustion engine, aside from the types of fuel they use, is how they ignite the fuel.
 petrol engine uses a spark plug to ignite fuel inside the cylinder.
A diesel engine uses a much higher compression ratio within the cylinder to heat the air inside.

I choose manual because you have more control than a automatic also i think it helps you become a better driver.
