Chapter 1

Question 1

How is FORCE measured and its equation?

Answer 1

In Newtons (N)

F = m x a

Question 2

How is MOMENTUM measured and its equation?

Answer 2

In kg m/s

Momentum = m (mass) x v (volume)

ANGULAR and LINEAR

Question 3

How is KINETIC ENERGY measured and its equation?

Answer 3

In Joules (J)

KE = 1/2 mv2

ENERGY
1 - Internal (fuel on board)
2 - Kinetic
3 - Potential

Question 4

How is WORK measured and its equation?

Answer 4

In Joules (J)

Work = Force x Distance

IT IMPLIES MOVEMENTS, WHICH IS DISTANCE.

Question 5

How is POWER measured and its equation?

Answer 5

In Watts (W)

Power = Work / Time

HOW FAST YOU DO THE WORK. ENERGY TRANSFERRED OVER TIME.

Question 6

What does the 1st Newton’s law consists of?

Answer 6

A body will remain at rest or in uniform motion unless acted on by an external force.

Question 7

What does the 2nd Newton’s law consists of?

Answer 7

The acceleration of a body in a straight line is proportional to the applied force and inversely proportional to the mass of the body.

Question 8

What does the 3rd Newton’s law consists of?

Answer 8

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

Question 9

What are the 4 forces implies in an aircraft when flying?

Answer 9

Lift,
Weight
(the largest ones)

Drag: Force opposes movement.
Thrust
(the shortest ones)
