Working on the Rocket

Construction of our Rocket

The biggest challenges we had when constructing our rocket were the fins and the cone. We were challenged when we were deciding how many fins we would be putting on our rocket. This was a problem because we didn't know if we should have glued our three fins or if we wanted to add a fourth. This was a problem when we were trying to place the fins to be glued onto the bottle. We also didn't know what we were going to make the cone out of to make it work for our rocket so it would be best for our rocket

When building our rocket we needed to take into consideration the size of the the fins. We also needed to consider how to build make the cone so it would be right for the rocket.

We think that our rocket will do good on it's launch. We also think that it will stay in the air for at least 10 seconds.

Definitions

Pressure: the continuous physical force exerted on or against an object by something in contact with it 

PSI: pounds per square inch.

Center Of Mass: a point representing the mean position of the matter in a body or system.

Propulsion: the action of driving or pushing forward

Newton's 1st Law: The first states that a body continues in a state of rest or uniform motion in a straight line unless it is acted on by an external force. 

Newton's 2nd Law: The second states that the rate of change of momentum of a moving body is proportional to the force acting to produce the change. 

Newton's 3rd Law: The third states that if one body exerts a force on another, there is an equal and opposite force (or reaction) exerted by the second body on the first.
