Study Notes
Physics and Matter
- Physics is the study of the fundamental nature of matter and energy, focusing on how they behave rather than why.
- Physics is essential for understanding how engines work, how airplanes and helicopters fly, and other phenomena in aviation and aerospace.
Matter
- Matter is the foundation of physics, and it is what all things are made of.
- Matter occupies space, has mass, and is perceptible to the senses in some way.
- According to the Law of Conservation, matter cannot be created or destroyed, but it can change its physical state.
Atomic Structure
- All matter is made up of atoms, which are the smallest units of matter that establish the unique characteristics of a substance.
- Atoms are composed of three main parts: protons, neutrons, and electrons.
- Protons have a positive electrical charge and are found in the nucleus of all atoms.
- Neutrons have no electrical charge and are also found in the nucleus of all atoms.
- Electrons have a negative electrical charge and orbit around the nucleus in concentric shells.
Elements
- Elements are unique kinds of matter made up of atoms with different physical attributes.
- There are over 100 different elements, each with its own unique characteristics.
- Elements are arranged in the periodic table, which groups them by periods and groups to show similar characteristics.
- Each element has a distinctive atomic number, abbreviation, and inherent properties.
Atomic Number and Mass
- The atomic number of an element is determined by the number of protons in its atoms.
- The mass of an atom is related to the number of characteristic subatomic particles that make it up.
- The number of subatomic particles in an atom defines the type of element it is and its inherent properties.
Understand the fundamental principles of physics and its applications in the field of aerospace, including the working of engines and flight of aircraft and helicopters.
