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.
