Propulsion - Turbine Engine Fundamentals

A body will retain at rest or continue it uniform motion in a straight line until acted upon by an external force.

• Newton's first law of motion

• Newton's second law of motion

• Newton's third law of motion

The acceleration of a body is directly proportional to the force applied to it and is inversely proportional to the mass of the body.

• Newton's first law of motion

• Newton's second law of motion

• Newton's third law of motion

Force developed by a gas turbine engine is proportional to?

• Mass of air flowing and acceleration given to that mass of air

• Weight of air flowing and speed given to that mass of air

• Flow of air injected and acceleration of the mass of air

For every action, there is an equal and opposite reaction.

• Newton's first law of motion

• Newton's second law of motion

• Newton's third law of motion

• Drag

• Thrust

What is unique to the definition of work?

• Does not mention time as being a factor

• Does not mention force as being a factor

• Does not mention distance as being a factor

One horsepower equals how much through one vertical foot in one minute?

• 33,000 lbs

• 550 lbs

What is the main difference between speed and velocity?

• Speed does not have direction
