Classical Physics

Classical physics is the study of matter and energy on a macroscopic scale, relying on deterministic, pre-1900 principles like Newton's laws and Maxwell's equations. It covers everyday phenomena, including motion, mechanics, thermodynamics, and electromagnetism. These theories are generally reversible and accurately describe the behavior of large, relatively slow-moving objects.

Key Aspects of Classical Physics

• Definition: Physical theories predating quantum mechanics and relativity, focusing on cause-and-effect.

• Core Theories:

  • Newtonian Mechanics: Studies motion, force, and gravity.
  • Electromagnetism: Maxwell's equations for light and electricity.
  • Thermodynamics: Heat and energy transfer.
  • Optics: Behavior of light.

• Deterministic Nature: Assumes that if the current state of a system is known, its past and future can be predicted.

• Limitations: Ineffective for microscopic (quantum) or extremely high-speed (relativistic) phenomena.

Key Founders:

• Isaac Newton: Formulated laws of motion and universal gravitation.
• James Clerk Maxwell: Developed electromagnetism.
• Other Contributors: Carnot, Joule, and Kelvin (thermodynamics).

Common Formulas:

• Newton's Second Law of Motion: \(F = ma\).
• Gravitational Force: \(F = G \frac {m_1 m_2} {r^2}\).
• Kinetic Energy: \(E_k = \frac{1}{2}mv^2\).
