Purpose

The students will investigate the effect of the rocket length upon the distance of flight. The students will also investigate the mass upon the distance flight. Background

The students will proof Newton's third law of motion states that for every action there is an equal and opposite reaction. Newton's third law also applies to rockets. A rocket gets its lift from the gases pushing out of its tail. The force of the rocket pushing on these gases is the action force. The gases exert an equal but opposite force on the rocket, which forces the rocket up, this is called the reaction force. According to the original guide sheet, the two items NASA will be evaluating the rocket on will be distance flown and time aloft. A two liter bottle with a cone and fins. The time is measured by seconds that the bottle flays, starting when it lives from the launch pad until it rites the ground. The distance is how far it flew. The motion will be projectile. The average velocity will be the total distance of rocket sting measured. The average speed will be the total distance of rocket flight measured in meters and total amount of time aloft measured in seconds. The altitude will be measured by an altimeter. The acceleration will speed up and change direction. The force can be the gravity. The kinetic energy will be the mass and velocity. The potential energy on the launch pad. Newton's first law is about the state of motion of an object does not charge as long as the net force acting on the object is zero. His second law is about the acceleration of an object is equal to the net force acting on it divided by the object's mass. Newton's third law is whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object. The momentum is mass × velocity. The kinetic energy is the mass × velocity. Momentum is a property of any moving object. For a slow moving object it is given by the mass times...
