✅ Fundamental physics terms along with their definitions:
1. Force: An interaction that causes an object to change its velocity, measured in newtons (N).
2. Mass: A measure of the amount of matter in an object, typically measured in kilograms (kg).
3. Acceleration: The rate of change of velocity of an object with respect to time, measured in meters per second squared (m/s²).
4. Velocity: The speed of an object in a specific direction, expressed in meters per second (m/s).
5. Energy: The capacity to do work, which can exist in various forms such as kinetic, potential, thermal, etc., measured in joules (J).
6. Work: The process of energy transfer that occurs when a force is applied to an object over a distance, calculated as the product of force and displacement.
7. Power: The rate at which work is done or energy is transferred, measured in watts (W).
8. Kinetic Energy: The energy possessed by an object due to its motion, calculated as KE = ½mv² .
9. Potential Energy: The energy stored in an object due to its position or configuration, commonly gravitational potential energy given by PE = mgh .
10. Momentum: The product of an object's mass and its velocity, representing the quantity of motion it possesses, calculated as p = mv .
11. Newton's First Law: An object at rest stays at rest, and an object in motion stays in motion with the same speed and direction unless acted upon by a net external force.
12. Newton's Second Law: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass, expressed as F = ma .
13. Newton's Third Law: For every action, there is an equal and opposite reaction.
14. Thermodynamics: The branch of physics that deals with heat, work, temperature, and the laws governing energy transfer.
15. Wave: A disturbance that transfers energy through space and matter, characterized by properties such as wavelength, frequency, and amplitude.
16. Frequency: The number of cycles of a wave that occur in a unit of time, measured in hertz (Hz).
17. Refraction: The bending of light or other waves as they pass from one medium to another due to a change in speed.
18. Electromagnetism: The branch of physics that studies the interaction between electric charges and magnetic fields.
19. Quantum Mechanics: The branch of physics that deals with the behavior of matter and light on the atomic and subatomic levels.
20. Relativity: A theory proposed by Albert Einstein that describes the laws of physics in relation to observers in different frames of reference, particularly regarding the effects of gravity and the speed of light.
