Questions:
Newtons Laws of Motion:
I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
II. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.
III. For every action there is an equal and opposite reaction.
Thrust Portion
Newton's 1st Law
Newtons first law applies to the rocket when it is at rest on the launch pad. When the force is applied the rocket slowed down but if the experiment was done in a vacuum it would have stayed in motion.
Newton's 2nd Law
Newtons second law applies to the rocket when it is shot up and there is a large accelerations. This acceleration changes to decelerate when the force begins to leave. The net force of the rocket is equal to the product of the mass and it's acceleration by the engine.
Newton's 3rd Law
Newtons third law applies to the force of ignition that acts on the fuel, then the fuel acts on the rocket. The fuel pushes the rocket which makes the rocket launch. As the rocket launches their is a downward force on the launch pad and the launch pad pushed back with the same amount of force sending the rocket into the air.
Glide Portion
Newton's 1st Law
Newtons first law applies to the rocket during the glide portion when the rocket is at it's final velocity of the thrust stage.The rocket would have remained at it's final velocity at the thrust stage, however, it was affected by the force of friction and the force of gravity, causing it to decelerate and come to a stop.
Newton's 2nd Law
The net force of the rocket is now negative since the only positive force (thrust force) is gone and the equation of F=ma supports the statement since a is now also negative to to gravity and friction.
Newton's 3rd Law
As the rocket continues to fly in the air, it pushed the air in front of it and the air pushes back, associating air friction and causing the rocket to decelerate.
Parachute Portion
Newton's 1st Law
The initial velocity of the rocket at this stage is 0 at the maximum height, therefore at rest. It would've stayed at rest, however, it was acted upon by the force of gravity which changed it's state of motion to downwards.
Newton's 2nd Law
The net force of the rocket is now negative since the only positive force (thrust force) is gone and the equation of F=ma supports the statement since a is now also negative due to gravity and friction
Newton's 3rd Law
As the rocket fly in the air towards the ground, it pushes the air in front of it and the air pushes back relating to air friction and causing the rocket to decelerate and crash into the ground slower than it would've.
