Advanced Certification Study Guide Level 2

Front

What is Newton's First Law of Motion?

Back

A body continues in its state of rest or of uniform motion in a straight line unless it is compelled to change that state by forces impressed upon it.

Front

What is Newton's Second Law of Motion?

Back

The rate of change of momentum is proportional to the force impressed and is in the same direction as that force.

Front

What is Newton's Third Law of Motion?

Back

To every action there is always an equal and opposite reaction.

Front

How does Newton's First Law apply to a rocket at rest on a launch pad?

Back

The rocket will remain at rest until a force (thrust) is applied to it.

Front

How does Newton's Second Law relate to rocket acceleration?

Back

The acceleration of a rocket is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is thrust in the context of rocketry?

Back

Thrust is the force that propels a rocket upward, generated by the expulsion of exhaust gases.

Front

Explain the concept of action and reaction in rocketry.

Back

When a rocket expels gas downwards (action), it experiences an upward force (reaction) that propels it into the air.

Front

What role does air resistance play in rocket flight?

Back

Air resistance opposes the motion of the rocket, affecting its acceleration and speed.

Front

Define momentum in the context of a rocket's motion.

Back

Momentum is the product of the rocket's mass and its velocity, influencing its motion and stability.

Front

What is the significance of the rocket's center of mass?

Back

The center of mass affects the rocket's stability and control during flight.
