### Top 20 Terms in Physics

1. Force
  The interaction that causes an object to accelerate or deform, measured in Newtons (N).

2. Mass
  The quantity of matter in an object, measured in kilograms (kg), which also influences gravitational attraction.

3. Acceleration
  The rate of change of velocity of an object, expressed in meters per second squared (m/s²).

4. Velocity
  The speed of an object in a particular direction, measured in meters per second (m/s).

5. Energy
  The capacity to perform work, existing in various forms such as kinetic, potential, thermal, and chemical, measured in Joules (J).

6. Work
  The energy transferred when a force is applied over a distance, calculated using the formula W = F × d (work = force × displacement).

7. Power
  The rate at which work is done or energy is transferred, measured in Watts (W).

8. Momentum
  The quantity of motion an object possesses, calculated as the product of mass and velocity, represented as p = m × v.

9. Friction
  The resistive force that opposes the motion of two surfaces in contact, influenced by the nature of the surfaces and the normal force.

10. Electric Charge
  A property of matter that causes it to experience a force when placed in an electromagnetic field, measured in Coulombs (C).

11. Magnetic Field
  A vector field surrounding magnetic materials and electric currents that exerts magnetic forces, measured in Teslas (T).

12. Temperature
  A measure of the average kinetic energy of the particles in a substance, measured in degrees Celsius (°C) or Kelvin (K).

13. Thermodynamics
  The branch of physics that deals with heat and temperature and their relation to energy and work.

14. Wavelength
  The distance between successive crests of a wave, typically measured in meters (m).

15. Frequency
  The number of occurrences of a repeating event per unit time, measured in Hertz (Hz).

16. Newton’s Laws of Motion
  A set of three fundamental principles that describe the relationship between the motion of an object and the forces acting on it.

17. Relativity
  A theory developed by Einstein that describes the relationship between space, time, and gravity, especially focused on the effects of traveling close to the speed of light.

18. Quantum Mechanics
  The branch of physics that studies the behavior of matter and energy at the smallest scales, where classical physics no longer applies.

19. Acoustic Waves
  Longitudinal waves that are generated by vibrating objects and propagated through a medium such as air or water.

20. Optics
  The branch of physics that studies the behavior of light, including its interactions with matter, and the construction and use of instruments that manipulate light.
