Key Concepts in Physics

Laws of Motion:
- Newton's First Law (Inertia): An object at rest remains at rest, an object in motion remains in motion, unless acted upon by an external force.
- Newton's Second Law (Force and Acceleration): Force is equal to the mass of an object multiplied by its acceleration.
- Newton's Third Law (Action and Reaction): For every action, there is an equal and opposite reaction.
Energy and Work:
- Kinetic Energy: The energy of motion.
- Potential Energy: The energy of position or stored energy.
- Conservation of Energy: The total energy of a closed system remains constant.
Waves and Vibrations:
- Types of Waves: Mechanical, electromagnetic, and sound waves.
- Wave Properties: Amplitude, frequency, wavelength, and speed.
