🌻important terms in physics for EUEE 1. Force: An interaction that causes an object to change its velocity, typically measured in newtons (N). 2. Mass: A measure of the amount of matter in an object, usually measured in kilograms (kg). 3. Weight: The force exerted by gravity on an object, calculated as the mass of the object multiplied by the acceleration due to gravity (W = mg). 4. Energy: The capacity to do work, which can exist in various forms such as kinetic, potential, thermal, and chemical energy. 5. Kinetic Energy: The energy possessed by an object due to its motion, calculated using the formula KE = 1/2 mv^2, where m is mass and v is velocity. 6. Potential Energy: The energy stored in an object due to its position or configuration, often associated with gravitational or elastic forces. 7. Work: The energy transferred to or from an object via the application of force along a displacement, calculated as W = Fd cos(θ), where F is force, d is displacement, and θ is the angle between the force and displacement vectors. 8. Power: The rate at which work is done or energy is transferred, measured in watts (W), where 1  W = 1  J/s. 9. Momentum: The quantity of motion an object has, defined as the product of its mass and velocity (p = mv). 10. Impulse: The change in momentum of an object when a force is applied over a period of time, calculated as J = F Δ t. 11. Acceleration: The rate of change of velocity of an object with respect to time, measured in meters per second squared (m/s²). 12. Newton’s Laws of Motion: Three fundamental principles that describe the relationship between the motion of an object and the forces acting on it:    - First Law: An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.    - Second Law: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).    - Third Law: For every action, there is an equal and opposite reaction. 13. Friction: The resistance encountered when one surface moves over another, which can be static or kinetic. 14. Thermodynamics: The branch of physics that deals with heat, work, temperature, and energy transfer. 15. Entropy: A measure of disorder or randomness in a system; in thermodynamics, it indicates the direction of spontaneous processes. 16. Electric Charge: A property of matter that causes it to experience a force in an electromagnetic field; charges can be positive or negative. 17. Voltage: The electric potential difference between two points in a circuit, measured in volts (V). 18. Current: The flow of electric charge in a circuit, measured in amperes (A). 19. Resistance: The opposition to the flow of electric current in a conductor, measured in ohms (Ω). 20. Ohm’s Law: A fundamental relationship in electrical circuits stating that V = IR, where V is voltage, I is current, and R is resistance. 21. Wave: A disturbance that transfers energy through space or matter, characterized by its wavelength, frequency, and amplitude. 22. Frequency: The number of cycles of a wave that pass a given point per unit time, measured in hertz (Hz). 23. Wavelength: The distance between successive crests (or troughs) of a wave, typically measured in meters. 24. Refraction: The bending of light as it passes from one medium to another due to a change in speed. 25. Reflection: The bouncing back of light or sound waves when they encounter a surface. 26. Gravity: A natural phenomenon by which all things with mass are attracted toward one another; described by Newton’s law of universal gravitation. 27. Quantum Mechanics: The branch of physics that deals with the behavior of particles on very small scales, such as atoms and subatomic particles.

☕️ important terms in geography for EUEE 1. Map: A visual representation of an area, showing physical features, political boundaries, or other geographical information. 2. Latitude: The geographic coordinate that specifies the north-south position of a point on the Earth's surface, measured in degrees from the Equator. 3. Longitude: The geographic coordinate that specifies the east-west position of a point on the Earth's surface, measured in degrees from the Prime Meridian. 4. Equator: An imaginary line that divides the Earth into the Northern and Southern Hemispheres, located at 0° latitude. 5. Prime Meridian: An imaginary line that divides the Earth into the Eastern and Western Hemispheres, located at 0° longitude. 6. Topography: The arrangement of the natural and artificial physical features of an area, including mountains, valleys, and plains. 7. Biome: A large ecological area on Earth’s surface with distinct plant and animal groups adapted to its environment, such as deserts, forests, and grasslands. 8. Climate: The long-term average of weather conditions in a particular area, including temperature, humidity, and precipitation. 9. Weather: The short-term atmospheric conditions in a specific area at a specific time, including temperature, humidity, precipitation, wind, and visibility. 10. Plate Tectonics: The theory explaining the movement of the Earth's lithosphere, which is divided into tectonic plates that interact at their boundaries. 11. Urbanization: The process by which rural areas develop into urban areas, often characterized by population growth and infrastructure development. 12. Migration: The movement of people from one place to another, often for reasons such as economic opportunity, conflict, or environmental factors. 13. Cultural Geography: The study of how cultural practices, beliefs, and values shape and are shaped by geographical space. 14. Ecosystem: A community of living organisms interacting with each other and their physical environment in a specific area. 15. Natural Resource: Materials or substances occurring in nature that can be exploited for economic gain, such as minerals, forests, water, and fossil fuels. 16. Sustainability: The practice of using resources in a way that meets current needs without compromising the ability of future generations to meet their own needs. 17. Cartography: The art and science of making maps, including the representation of spatial information. 18. Glacier: A large mass of ice that moves slowly over land, formed from compacted snow. 19. Delta: A landform created by sediment deposition at the mouth of a river where it meets a body of water. 20. Archipelago: A group or chain of islands clustered together in a body of water. 21. Desertification: The process by which fertile land becomes desert as a result of drought, deforestation, or inappropriate agriculture. 22. Biodiversity: The variety of life in a particular habitat or ecosystem, encompassing different species of plants, animals, and microorganisms. 23. Gentrification: The process by which urban neighborhoods undergo transformation through an influx of more affluent residents, often leading to displacement of lower-income residents. 24. Globalization: The process by which businesses or other organizations develop international influence or operate on an international scale, affecting cultural and economic landscapes. 25. Demography: The statistical study of populations, including the structure, distribution, and trends in population changes. 26.
