Study Notes
Vector Operations in Algebra for Aviation
Vector Addition
- In aviation, vector addition is used to calculate the resultant velocity of an aircraft when it is affected by multiple forces such as wind and thrust.
- Vectors are added by combining their corresponding components.
- The resultant vector is the sum of the individual vectors.
Vector Subtraction
- Vector subtraction is used to find the difference between two vectors.
- It is used in aviation to calculate the change in velocity of an aircraft.
- To subtract vectors, subtract the corresponding components of the two vectors.
Scalar Multiplication
- In aviation, scalar multiplication is used to scale vectors by a constant factor.
- It is used to calculate the change in velocity of an aircraft when it is affected by a constant force.
- Scalar multiplication is commutative, associative, and distributive.
Vector Magnitude (Length)
- The magnitude of a vector is its length or size.
- In aviation, vector magnitude is used to calculate the speed of an aircraft.
- The magnitude of a vector can be calculated using the Pythagorean theorem.
Unit Vectors
- A unit vector is a vector with a magnitude of 1.
- In aviation, unit vectors are used to represent directions.
- Unit vectors are used to simplify vector calculations and to find the direction of a vector.
Vector Resolution
- Vector resolution is the process of breaking down a vector into its component parts.
- In aviation, vector resolution is used to calculate the horizontal and vertical components of an aircraft's velocity.
- Vector resolution is used to simplify complex vector calculations.
Relative Motion
- Relative motion is the motion of an object relative to another object.
- In aviation, relative motion is used to calculate the motion of an aircraft relative to the wind or other objects.
- Relative motion is calculated using vector subtraction and addition.

Mechanics
Kinematics
- Displacement is the change in position of an object
- Velocity is the rate of change of displacement
- Acceleration is the rate of change of velocity
- Distance is the total length of path traveled by an object
- Speed is the rate of change of distance
Dynamics
- Force is a push or pull that causes an object to change its motion
- Newton's First Law: an object at rest will remain at rest, and an object in motion will continue to move, unless acted upon by an external force
- Newton's Second Law: force is equal to the mass of an object multiplied by its acceleration (F = ma)
- Newton's Third Law: for every action, there is an equal and opposite reaction
Energy and Work
- Energy is the ability to do work
- Kinetic Energy is the energy of motion
- Potential Energy is the energy of position or stored energy
- Work is the transfer of energy from one object to another
- Efficiency is the ratio of output energy to input energy
Thermodynamics
Temperature and Heat
- Temperature is a measure of the average kinetic energy of particles in a substance
- Heat is the transfer of energy from one body to another due to a difference in temperature
- Heat Transfer occurs through conduction, convection, and radiation
Laws of Thermodynamics
- Zeroth Law: if two systems are in thermal equilibrium with a third system, they are also in thermal equilibrium with each other
- First Law: energy cannot be created or destroyed, only converted from one form to another
- Second Law: the total entropy of a closed system always increases over time
- Third Law: as the temperature of a system approaches absolute zero, its entropy approaches a minimum value
Gas Laws
- Boyle's Law: the volume of a gas is inversely proportional to its pressure (PV = constant)
- Charles' Law: the volume of a gas is directly proportional to its temperature (V/T = constant)
- Gay-Lussac's Law: the pressure of a gas is directly proportional to its temperature (P/T = constant)
