A.Understanding Physics
Physics is a branch of science that studies matter, energy, and the fundamental laws that govern
how the universe works. It seeks to understand everything from the smallest particles that make up atoms
to the vast structures of galaxies in space. Physics explains why objects move, how forces act, how light
travels, why electricity flows, and how heat is transferred. By observing natural phenomena and using
mathematics, physics helps us describe and predict events such as falling objects, the behavior of waves,
or the motion of planets. The discoveries in physics form the basis of modern technology such as
electricity, computers, communication systems, machines, and even medical equipment. In essence,
physics helps us understand the nature of reality and the principles that keep the universe in order.
B.Types of Physics
1.Classical Mechanics
• Studies motion, forces, and energy.
• Explains how objects move in daily life and how planets orbit.
2.Thermodynamics
• Focuses on heat, temperature, and energy transfer.
• Used to understand engines, refrigerators, and weather.
3.Electromagnetism
• Studies electricity, magnetism, and light.
