We have started to make our rockets we need a 1.5 lliter bottle. and a ice cream container to make our fins. we cut out our fins and glued them onto our rocket we went out for a test flight our furthers we got was 15 meters. we used a force of 60 psi and a water level of 300ml. also before we started making our rockets we made paper planes to test out how far they go. we also had to cheek the aerodynamics of the bottle and cheek the fins we had to see how balenced our rocket was. we conected our rocket to the pump to pump it us so it had some thrust to get it off the ground. then is was blast off. we havent done our final blast off yet because the pump didn't work
Newtons laws
His first law, an object will not change its motion unless a force acts on it. The second law, the force on an object is equal to its mass times its acceleration. The third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
