Key Concepts in Physics

Kinematics: Study of motion without considering forces; includes concepts like displacement, velocity, and acceleration.
Dynamics: Examines forces and their effects on motion; includes Newton's laws of motion.
Work and Energy: Work is the product of force and displacement; energy exists in various forms (kinetic, potential, thermal).
Conservation Laws: Energy and momentum are conserved in isolated systems.

Laws of Thermodynamics:
- First Law: Energy cannot be created or destroyed, only transformed.
- Second Law: Entropy of an isolated system always increases.
- Third Law: As temperature approaches absolute zero, entropy approaches a constant minimum.
Heat Transfer: Conduction, convection, and radiation are the three modes of heat transfer.

Wave Properties: Includes frequency, wavelength, amplitude, and speed.
Types of Waves:
- Mechanical Waves: Require a medium (e.g., sound waves).
- Electromagnetic Waves: Do not require a medium (e.g., light waves).
Interference and Diffraction: Phenomena that occur when waves overlap, leading to constructive or destructive interference.

Electric Charge: Fundamental property of matter; can be positive or negative.
Ohm's Law: V = IR (Voltage = Current × Resistance).
Magnetic Fields: Produced by moving charges; affect charged particles and currents.
Electromagnetic Induction: The generation of electric current from a changing magnetic field.

Quantum Mechanics: Describes physical phenomena at atomic and subatomic levels; includes uncertainty principle and wave-particle duality.
Relativity: Einstein's theories of special and general relativity; includes concepts of spacetime and the effects of gravity on time.
Nuclear Physics: Study of atomic nuclei, radioactivity, and nuclear reactions.

Cosmology: Study of the universe's origin, evolution, and eventual fate.
Stellar Evolution: Life cycle of stars, including processes like nuclear fusion and supernovae.
Black Holes: Regions of spacetime with gravitational pulls so strong that nothing can escape.

Kinematic Equations:
- ( v = u + at )
- ( s = ut + \frac{1}{2}at^2 )
- ( v^2 = u^2 + 2as )
Work: ( W = F \cdot d \cdot \cos(\theta) )
Kinetic Energy: ( KE = \frac{1}{2}mv^2 )
Potential Energy: ( PE = mgh )
Ohm's Law: ( V = IR )

Kinematics: Analyzes motion in terms of displacement, velocity, and acceleration without considering forces.
Dynamics: Focuses on forces and their impact on motion; based on Newton's laws that describe the relationship between an object and the forces acting on it.
Work and Energy: Work is calculated as the product of force applied and displacement in the direction of the force. Energy exists in multiple forms: kinetic (energy of motion), potential (stored energy), and thermal (energy due to temperature).
Conservation Laws: In isolated systems, both energy and momentum remain constant.

First Law: States that energy is neither created nor destroyed; it is only transformed from one form to another.
Second Law: Indicates that the entropy, or degree of disorder, of an isolated system will always increase over time.
Third Law: As temperature approaches absolute zero, the entropy of a system approaches a minimum value.
Heat Transfer: Occurs through three main processes: conduction (heat transfer through direct contact), convection (heat transfer through fluid movement), and radiation (heat transfer through electromagnetic waves).

Wave Properties: Key characteristics of waves include frequency (number of vibrations per second), wavelength (distance between consecutive crests), amplitude (height of the wave), and speed (rate at which the wave travels).
Types of Waves:
- Mechanical Waves: Requires a medium for propagation; sound waves are a prime example.
- Electromagnetic Waves: Do not require a medium; examples include light waves and radio waves.
Interference and Diffraction: Occurs when waves overlap, resulting in patterns of constructive (waves combine) or destructive interference (waves cancel each other).

Electric Charge: A fundamental attribute of matter categorized as positive or negative, leading to electrostatic interactions.
Ohm's Law: Describes the relationship between voltage (V), current (I), and resistance (R) as V = IR.
Magnetic Fields: Generated by moving electric charges, influencing other charged particles and currents in their vicinity.
Electromagnetic Induction: The process through which a changing magnetic field generates an electric current.

Quantum Mechanics: Explains phenomena on atomic and subatomic levels, highlighting principles such as the uncertainty principle and wave-particle duality.
Relativity: Einstein's theories of special relativity and general relativity introduce concepts of spacetime and the influence of gravity on the passage of time.
Nuclear Physics: Investigates atomic nuclei, their interactions, radioactivity, and processes involving nuclear reactions.

Cosmology: Analyzes the origins, evolution, and ultimate fate of the universe.
Stellar Evolution: Examines the life cycle of stars, outlining stages like nuclear fusion and explosive events like supernovae.
Black Holes: Regions in spacetime where gravitational forces are so intense that not even light can escape.

Kinematic Equations:
- ( v = u + at ) (final velocity)
- ( s = ut + \frac{1}{2}at^2 ) (displacement)
- ( v^2 = u^2 + 2as ) (relationship between velocity and acceleration)
Work: ( W = F \cdot d \cdot \cos(\theta) ) (work done by a force)
Kinetic Energy: ( KE = \frac{1}{2}mv^2 ) (energy of motion)
Potential Energy: ( PE = mgh ) (stored energy in a gravitational field)
Ohm's Law: ( V = IR ) (relationship in electrical circuits)
