Classical Mechanics examines motion, forces, and energy, providing foundational principles for understanding movement.
Electromagnetism studies the interactions between electric charges and magnetic fields, crucial for electrical engineering and technology.
Thermodynamics focuses on the laws governing heat, energy transfer, and their implications in various systems.
Quantum Mechanics explores the behavior of particles at atomic and subatomic levels, challenging classical intuitions of reality.
Relativity, consisting of Special and General Relativity, describes how gravity interacts with space-time, revolutionizing our conception of the universe.

Force represents the interaction that leads to a change in an object's motion; can be calculated using Newton's second law.
Energy is defined as the capacity to perform work, existing in forms like kinetic, potential, and thermal energy.
Work is quantified as the product of force applied and the displacement of the object in the direction of that force.
Momentum, defined as mass multiplied by velocity, is a conserved quantity in isolated systems, foundational to collisions and dynamics.
Waves are energy-carrying disturbances that can be categorized as transverse (oscillations perpendicular to direction) or longitudinal (oscillations parallel to direction).

Newton's Laws of Motion include three essential principles governing how objects respond to forces:
- An object remains at rest or in uniform motion unless acted upon by a net force.
- Force equals mass times acceleration (F = ma), establishing a relationship between acceleration and the forces acting on an object.
- For every action, there is an equal and opposite reaction, illustrating the interconnectivity of forces.
Conservation of Energy states that energy is neither created nor destroyed, only transformed from one form to another.
Conservation of Momentum indicates that the total momentum in an isolated system is constant throughout interactions and collisions.

Kinematic equations describe motion, including:
- ( v = u + at ), where v is final velocity, u is initial velocity, a is acceleration, and t is time.
- ( s = ut + \frac{1}{2}at^2 ), where s represents displacement.
The Work-Energy Theorem states that the work done on an object equals the change in its kinetic energy: ( W = \Delta KE = KE_{final} - KE_{initial} ).
Ohm’s Law relates voltage (V), current (I), and resistance (R) in electrical circuits: ( V = IR ).

Force is measured in Newtons (N), representing mass times acceleration.
Energy is quantified in Joules (J), the work necessary to move an object.
Power, indicating the rate of energy transfer, is measured in Watts (W).
Electric Charge is expressed in Coulombs (C), defining the quantity of electricity.
Mass is represented in kilograms (kg), the measure of matter in an object.
