im doing this project for school and we are doing space
and for our homework we have to find things out about rockets so do you know what makes the rocket go up in the sky?

Thrust, which is the force that you get by ejecting mass (exhaust gases, liquids, bullets) all the time.
Thrust = mass flow * average exhaust velocity
mass flow is the amount of mass you throw every second. If you throw a brick of one kg mass every second out of the back of a car, you produce a mass flow of 1 kg/s.
Even small rocket engines that you can buy from model rocket stores have exhaust velocities of about 6000 km/h, the most effective rocket engines reach 16000 km/h.
And big rocket engines, like for example the one that propelled the rocket NASA launched this week, named Ares I-X, burn easily many tons of fuel per second and eject the hot exhaust gases (of the same mass as the fuel you have burned) through the nozzle. And the space shuttle gets it's propellants from the tank through two large pipes with 40 cm diameter.
You don't need air to push against for producing thrust, actually, all rocket engines work better in vacuum, because air slows the exhaust. Rocket engines push against their own exhaust for moving forward.

Yep, inertia. Newt's law one say to the effect "It takes a net force to change the momentum of inertial mass." p = mv is the momentum of a mass (e.g., rocket) traveling at velocity v. As there is no net force (discounting gravity as a possible force) p = constant = mv; so v = constant.
Newton's third law of motion: Every action has an equal and opposite reaction.
The energy that is being thrust out the engine also pushes up on the rocket, propelling it into the sky.

Pointing the nose in the direction of the sky, along with having sufficient thrust to overcome gravity.

newton's third law of motion... for every action there's an equal and opposite reaction... thrusters fire in one direction (downward in this case) and the rocket moves in the opposite direction (downward)

Launch the rocket, and stay at the window for the show!
Remember you have to exit the way you came, which means avoiding the trip mine staircase!
If you need to re-jog your memory but can't think, have a look at this site it's a complete walk through for the game. But as written by the person who submitted the info: "Please, DO
NOT READ FROM START TO FINISH. If you do, you'll just ruin the game. And this is one heck of a game - so try not to spoil it.
Half-life: Walk through
Three basic tips can help you get started.
First, even if you are an experienced HEV suit user, you should avail yourself of the Hazard Course. It teaches you how to use the suit (the equivalent of armor in other games) to its fullest advantage, and that special long jump module could save your life.
Second, as Black Mesa deals with a wide variety of "special" experiments, it is important to remember that many useful items are stored in the plethora of wooden crates and containers throughout the lab. Smash 'em all and look inside-but avoid the ones marked "Explosives" if you know what's good for you.
Third, remember that the guards and scientists are your friends; they can watch your back, heal you, and even get you out of a sticky situation. Often, if one dies, you cannot continue. Save early and often."
