Eternal God,
Who makes the winds and clouds obey,
You protect the eagle in it’s flight,
And the dove seeking safety.

Uphold me as I soar above land and sea,
Pilot my ship safely through the sky.

Be with me at takeoff and landing,
And let me not lose my way.

Above all,
Keep me in your grace,
And let my last landing bring me
Safely into your hangar,
Redeemed to fly with you,
Eternally.

Amen.

The Effects of Weight in Flight

Air is the invisible mixture of gases which surrounds us in our everyday lives. Air is a mixture of gases consisting of Nitrogen, Oxygen, Argon, Carbon Dioxide and Water V***r. Like all matter, air has weight and takes up space. However, it can also be compressed, unlike solids and liquids.

This occurs due to inertia. The higher the mass and size of an object is, the larger the impact inertia will have on it. Similarly, during flight added weight causes higher landing speeds since the aircraft has become more massive and requires a greater air resistance to slow down.

Since Air is a mixture of gases, it adheres to the particle theory and expands when heated and condenses when cooled. Hot elements rise while cool elements move downwards. This is why when the burner in a hot air balloon is activated the balloon inflates and rises up in the air. As well, Air is subject to changes in pressure and density which can drastically influence its base properties.

Thrust is the force applied normal or perpendicular to a surface which causes the acceleration of said mass. The sum of the mass and experienced velocity of the object is called momentum.

Acceleration is a very different concept from velocity and speed. Acceleration is the increase of an object's speed per unit time. Where as speed is the rate at which an object is able to move. In turn, Momentum is the sum of the velocity and mass which an object is subject to.

The momentum which an aircraft develops is the sum of the forces which carry it through the air and allow it to propel itself forward.

Hello Guys I'm back! I will post important things soon. Again this is Eng'r. Arjay Ansag.

Centripetal Force

Any motion in a curved path represents accelerated motion, and requires a force directed toward the center of curvature of the path. This force is called the centripetal force which means "center seeking" force. The force has the magnitude

Swinging a mass on a string requires string tension, and the mass will travel off in a tangential straight line if the string breaks.

The centripetal acceleration can be derived for the case of circular motion since the curved path at any point can be extended to a circle.

Note that the centripetal force is proportional to the square of the velocity, implying that a doubling of speed will require four times the centripetal force to keep the motion in a circle. If the centripetal force must be provided by friction alone on a curve, an increase in speed could lead to an unexpected skid if friction is insufficient.

Hello everyone! I'll be posting some important topics about Aviation Physics soon... Good Day!

Congratulations AMT I-747 Students...👍👏👏👏
Student teams build and launch a rocket made out of a soda bottle and powered with an air pump and consider the forces on a rocket, Newton's Laws, and other principles and challenges of actual space vehicle launch.

Rocket Launch encourages:

TEAMWORK
Working with others to meet challenges

COMMUNICATION
Listening and responding appropriately to others & negotiation skills

UNDERSTANDING
Knowledge of the key elements of enabling flight

SAFETY
Developing the ability to assess risk and apply control measures

ANALYSIS
Recording and examining results, predicting outcomes

Temperature is an objective measurement of how hot or cold an object is. It can be measured with a thermometer or a calorimeter. It is a means of determining the internal energy contained within the system.

Because humans instantly perceive the amount of heat and cold within an area, it is understandable that temperature is a feature of reality that we have a fairly intuitive grasp on. Indeed, temperature is a concept that arises as crucial within a wide variety of scientific disciplines.

Consider that many of us have our first interaction with a thermometer in the context of medicine, when a doctor (or our parent) uses one to discern our temperature, as part of diagnosing our illness.

A new year is all about starting afresh and realising your dreams. So, let’s raise a toast to a Happy New Year and even happier beginnings. Take inspiration from these quotes to help you get started and if you are inspired enough, share your enthusiasm with your loved ones.
HAPPY NEW YEAR AVIATORS!!!

Merry Christmas Everyone... God Bless you All...
