Physics is the natural science that studies matter, energy, and the interactions between them. It is one of the oldest academic disciplines and has applications in many fields, from engineering to medicine.
Basic Concepts
- Matter: Anything that has mass and occupies space.
- Energy: The capacity to do work or cause change.
- Force: A push or pull that causes an object to change its state of motion or shape.
Branches of Physics
- Classical Mechanics: Studies the motion of objects under the influence of forces.
- Electromagnetism: Studies electric and magnetic fields and their interactions with matter.
- Thermodynamics: Studies the relationships between heat, work, temperature, and energy.
- Quantum Mechanics: Studies the behavior of particles at the smallest scales.
