1
Q

What is speed?

A

Speed is the rate of change of distance

2
Q

How many metres are there in 1nm?

A

There are 1852ft in 1nm.

3
Q

How many feet are there in 1 nautical mile?

A

There are 6080ft in 1 nautical mile

4
Q

How many metres per second are there in 1kt?

A

0.5144

5
Q

What is the definition of acceleration?

A

Acceleration is the rate of change in velocity. Acceleration requires a force in order to be achieved.

6
Q

What is the equation for acceleration?

A

F= ma

7
Q

What is Mass?

A

Mass is the quantity of matter a body possesses. The SI unit is Kg or lb.

8
Q

What is force measured in?

A

Force is measured in Newtons.

9
Q

What is momentum?

A

Momentum is the product of an objects mass times its velocity.

10
Q

What is the equations for momentum?

A

P=m/v

11
Q

What is weight?

A

Weight is the force that a mass exerts when in a gravitational field. (9.81m/s on earth).

12
Q

What is kinetic energy?

A

Kinetic energy is the energy that a mass possesses due to its motion.

13
Q

What is the equation for kinetic energy?

A

K=1/2mV2

Where: m = mass; V = velocity.

14
Q

What is work?

A

Work is done when energy is transformed from one form to another

15
Q

What is the equation for work?

A

Work = Force x Distance

Force is measured in m/s.

16
Q

What is power?

A

Power is the rate of doing work.

17
Q

How is Power calculated?

A

Power is calculated as Force/True Air Speed (TAS).

As power is the rate of doing work:

Power = work/time, therefore:

Power = force x distance/time, therefore:

Power = force x speed (TAS)
