Motion and Pressure
Pressure=FxD
Gas particles are all around us but we cant see them and they bounce around the place e.g take a plastic bottle for example when you breath on all the air inside the gas particles around the bottle start to push in so the bottle is crushed.
Electricity and magnetism
There are two different types of electrical charges one in positive charge and the other is negative charge
If you rub a balloon on a woolly jumper all the electrons from the jumper will go to the balloon
If you have a lot electrons in your balloon the positive and negative charges will attract together.
Pressure is how much force there is on a certain area. If you exert a big force on a small area the pressure will be large.
