HOVERCRAFT PROJECT

materials

1 meter square piece of wood

2.5 meter long heavy duty rubber

heavy duty staples

duck tape

rubber tube

metal connection pieces

blower chair

hammer

drill

ruler

super glue

plastic pieces (to connect the blowers)

how to construct

First you need a square peace of wood then you have to cut that into a circle after that you make a hole in one edge of the circle then you get the rubber band and the cloth and you put them together and at the bottom. On the cloth you make 3 holes in the middle of the circle.Then you put the tube for the blower. then you put the bower and tighten it and after you are done with that part you get 2 peace of wood and connect it to the chair and then you connect the other blowers to those woods.

updating

we upgraded the hovercraft by adding two more blowers on the side that allows it to move. because in our first version it only had one blower as you can see on the first picture then we add the ones on the second picture.

how it works

hovercraft is not something that is really easy to operate.you have to be trained professionals like us and have to have a hovercraft license.to operate it first you must sit on the chair and get you balance and then you need to turn on the blower at the bottom after that you are supposed to stay still so the

hovercraft dosen't lose its balance.and after that you could turn on the other blowers on the sides to make the hovercraft move.

safety

1-because the hovercraft travels with incredible speeds its really dangerous.

you shouldn't sit any where but the middle because then it will lose its balance.

2-you shouldn't move allot.

3- you shouldn't stand on it.

principle

Hovercraft is an object that needs newtons 1st,2nd, and 3rd law. it also uses static and kinetic energy.

newtons 1st law

the velocity of the object stays constant unless there is a an external force being used on the object.

in our project the hovercrafts velocity is zero so when you apply a little force ,because of its inertia it moves.

newtons 2nd law

the acceleration of an object is directly proportional to the net force and inversly proportional to the mass.in our project if you dont turn on the hovercraft you cant move it but when its on you only need a little force to move.

newtons 3rd law

if there is a force being used there is always an opposite force.

in our project the ground makes an opposite force to the air flow thats coming out from the hovercraft and makes it hover.

friction

Every object that has a mass has a friction on the surface it is standing. a friction an object has depends on its weight and the ground its on.

static force of friction

static force of friction is when an object is in a uniform motion, it has static friction. that means when an object does not move it is in static force of friction.

kinetic force of friction

kinetic force of friction is when an object is moving, it has kinetic energy. that is why it is in kinetic force of friction.

coefficient of friction

the dependence of frictional force on the particular surface in contact is called the coefficient of friction.

force of friction

if we do not turn on the blower because of the friction there we cannot push the hovercraft but when we turn on the blower the friction decreases so it would be easier to push it.
