The physics of car racing

1. What has been done to make this a fair test?
we all have the same car

2. What forces are needed to make the car go faster and how have you modified car accordingly?
Gravity, push, acceleration, thrust.

3. What forces are needed to to make the car stop and what adjustments have you made to try and stop it by the line? My group tried to put rubber bands on to slow it down.

4. What forces are needed to make the car travel further and what adjustments have you made to achieve this? We put a rock on the car so it goes slower.

Wind and lift

What causes the wind?

We saw in our experiment that heat cause air, or water, to move. This is the same force that make the wind. The sun heats up the earth, and that causes the air to heat up. That hot air then moves upwards, and other cold air has to move in to place. This movement of the air is the wind

                            The picture above shows how it works with the sun causing the warm air



Effects of the wind

If we had no wind the weather wouldn't change it would always rain and be sunny outside so that's why we have wind so the weather can change.

how wind helps us   

if we go sailing it can help us go the way we want and it will make us more so we do not stay in one place and we can go to were we want to go. And it can help us with so much more in stuff that we need to do.

Physics of car racing

1. What i tried today why I tried it
I tried to put a rubber band and a balloon on my car to make it slower and straight.

2. What happened when I tried to race it
It flipped around.

3.What will I try next time
to make it faster.

4.What research did I do
how to make it go slower and straight.

Cars

1. What problem does our car already have
It is to fast

2. How do you think your car will go faster
Put a rock on it

3. How do you think your car will slow down
Sand paper

4. What equipment we need
Car, Rock, Paper, Sandpaper

The physics of Tug of war

Concrete
Carpet
Grass
Lino



Concrete
My prediction for Concrete has the most grip because of the friction.


Carpet
My prediction for the carpet is that we might slip.


Grass 
My prediction for the grass is that we will slip because of the mud and the dirt and it is not like the carpet.


Lino 
My prediction for the lino is that we wont slip because of our shoes that we were wearing.


I think the best to do tug of war on is concrete because it is less slippery then carpet grass and lino. 

What is a simple machine

A machine is a system that changes the relationship Between effort (the force applied) and load (the weight Lifted or moves) 

Machines make our lives easier.

Machines help us to lift,push,pull,turn,cut & join things.

Wheels,rollers,levers,gears and pulleys all make it easier to move a heavy load by reducing friction or magnifying forces
