Classical Mechanics Fundamentals
Classical mechanics describes the motion of macroscopic objects under the influence of forces. Newton's three laws of motion form the foundation: an object at rest stays at rest (inertia), force equals mass times acceleration (F = ma), and every action has an equal and opposite reaction. Kinematic equations connect displacement, velocity, acceleration, and time for uniformly accelerated motion.
Energy Conservation in Physics
The law of conservation of energy states that energy cannot be created or destroyed, only transformed. Kinetic energy (½mv²) represents energy of motion, while potential energy (mgh for gravity, ½kx² for springs) represents stored energy. Work (W = Fs cos θ) is the mechanism by which energy is transferred between objects. These principles apply from subatomic particles to planetary orbits.
